Definitions
WPM, KDPH, CPM — defined
Three metrics, one skill. Each maps to a different exam standard and a different way you'll be scored.
K
KDPH
Key Depressions Per Hour
KDPH counts every keystroke you make in one hour. The Staff Selection Commission adopted it as the official metric for central government exams. A space, backspace, or character each counts as one key depression.
KDPH = WPM × 5 × 60
e.g. 35 WPM = 10,500 KDPH
W
WPM
Words Per Minute
WPM measures how many 5-character groups you type per minute. Most typing platforms, job listings, and speed tests use it. One "word" is 5 keystrokes regardless of actual word length.
WPM = KDPH ÷ 300
e.g. 8,000 KDPH = 26.7 WPM
C
CPM
Characters Per Minute
CPM is the raw keystroke count per minute, equal to WPM × 5. Some exams and data-entry job descriptions use CPM or KPH (Keystrokes Per Hour, which equals KDPH) instead of WPM. The numbers differ; the speed they measure does not.
CPM = WPM × 5
e.g. 35 WPM = 175 CPM

Why India uses KDPH instead of WPM
The Staff Selection Commission standardised its typing test in the late 1990s and chose Key Depressions Per Hour because it measures raw throughput — every keystroke counted, no dependence on word boundaries or passage vocabulary. A fast typist cannot inflate KDPH by choosing short words; the metric captures what you actually pressed. Railway Recruitment Boards, Banking institutes (IBPS), LIC, and state PSC boards adopted the same unit so scores could be compared across millions of candidates. KDPH is now the standard unit for any Indian government typing test.

Metric guide
Four numbers on your screen. Each one has a job.
The converter shows all four at once. Each metric maps to a different exam or job standard.
KDPH
Key Depressions Per Hour
The official Indian government exam standard. Counts every individual keystroke — characters, spaces, punctuation — across a full hour of typing. Used by SSC, Railway RRB, IBPS, LIC, India Post, EPFO, and most state PSC boards.
WPM × 5 × 60
Your exam scorecard shows KDPH. Train toward this number, not WPM.
WPM
Words Per Minute
The global standard for typing speed. One word = 5 keystrokes by SSC definition. Used on most typing platforms (Monkeytype, TypeRacer, 10FastFingers), global job listings, and US/UK government assessments.
KDPH ÷ 300
Compare speeds across platforms in WPM. Convert to KDPH before checking exam cutoffs.
CPM
Characters Per Minute
Raw keystrokes per minute. Equal to WPM × 5. Some BPO and data-entry roles specify CPM in job descriptions. Court exams in some states use CPM directly, counting every character including spaces, rather than converting to KDPH.
WPM × 5
Relevant for court clerk and BPO roles. CPM × 60 = KDPH.
KPS
Keystrokes Per Second
Keystrokes per second. Rare in exam scoring but useful for spotting rhythm breaks. A typist at 10,500 KDPH averages 2.92 keys per second.
KDPH ÷ 3600
If your KPS drops sharply mid-passage, that's where your weak keys are. Use it to find your slowdown pattern.
Why this matters
Practiced in WPM. Tested in KDPH. That gap costs people the job.
You practice in WPM. The government scores you in KDPH. Candidates who conflate the two fail tests they had the speed to pass.
Government exams use KDPH, not WPM
SSC, Railway, and Banking exams score in Key Depressions Per Hour, a metric most typing platforms don't show. Candidates who don't know their KDPH find out they're short on exam day.
One wrong number can disqualify you
SSC CHSL requires 8,000 KDPH. Candidates who train to "26 WPM" sometimes fall short because 26 WPM = 7,800 KDPH — 200 below the cutoff. Without the exact number, you don't know you're failing until exam day.
Different exams, different formulas
SSC uses 5 key depressions per word. Court exams may use characters per minute. Some state PSC boards use their own formula. This converter covers all three.
Global professionals need both metrics
Data entry roles globally advertise speeds in CPM or KPH. Knowing all three metrics — WPM, KDPH, CPM — lets you read any job spec or exam notification without guessing.

Accuracy & scoring
Raw KDPH isn't your final score
Every exam deducts for errors. Your net score after penalties is what the examiner reads — not the number this converter shows.
Half-mistake rule (SSC standard)
−0.5 per error
SSC CHSL, SSC CGL DEO, and most central exams apply a half-mistake deduction: each wrong or extra word reduces your net word count by 0.5. At 8,000 KDPH with 5% errors you may score below the cutoff even though your raw speed exceeds it.
Full-mistake rule (some state exams)
−1 per error
Several state PSC boards and High Court exams deduct a full word for every mistake. A 10% error rate at 35 WPM effectively drops you to ~31.5 WPM — that's the difference between clearing and failing Railway NTPC.
Backspace restrictions
Varies by exam
Some exams (e.g., CPCT Madhya Pradesh) disable the backspace key entirely. Others count each backspace as an additional key depression without credit. This can inflate your gross KDPH while reducing net accuracy — always check the official exam notification.
Passage difficulty variance
Indirect impact
Official exam passages include proper nouns, compound words, and punctuation-heavy sentences that are harder to type than standard practice text. Candidates often score 10–15% lower on exam day than on familiar practice passages.
Network and system lag
Indirect impact
Online exams introduce keystroke buffering latency that offline practice doesn't. Fast typists above 60 WPM are most affected. If you're near the cutoff, build a 10–15% speed buffer to absorb exam-day conditions.
Different character count methods
Exam-specific
SSC uses 5 key depressions per word. Some court exams count each character including spaces individually. A few state exams use syllable-based counting for Hindi. Always verify the exact formula in the official notification — never assume SSC rules apply.
The formula examiners use
Net KDPH = (Gross words − 0.5 × Errors) × 5 × 60
Example
200 words, 10 errors → (200 − 5) × 300 = 58,500 net keystrokes/hr

Why candidates fail
Fast enough to pass. Still failing.
Speed isn't the gap. Most candidates fail because they misread what the exam measures.
01
Training in WPM, tested in KDPH
Candidates hit 30 WPM on Monkeytype and assume they're ready for SSC CHSL (8,000 KDPH). But 30 WPM = 9,000 KDPH — only 1,000 above the cutoff, with no buffer for errors or exam-day lag. Know both numbers before you call yourself ready.
Fix:
If the exam needs 8,000 KDPH, train until you consistently hit 10,500+ (35 WPM). The 30% buffer absorbs errors, lag, and hard passages.
02
Ignoring error deductions
SSC deducts 0.5 words per mistake. A candidate typing 1,500 words in 10 minutes with 50 errors nets only 1,475 words — a 1.7% accuracy drop that translates to ~250 fewer KDPH. At the 8,000 cutoff, that's the difference between pass and fail.
Fix:
Train accuracy before speed. At 98%+ accuracy, push pace. Errors cost more time than slowness.
03
Practicing on easy text, tested on hard passages
Typing platforms use dictionary words. Official SSC and Railway passages contain proper nouns (Jawaharlal, Rajasthan, Comptroller), numbers written out (five thousand three hundred), and punctuation-heavy sentences. That difficulty gap cuts speed by 10–15%.
Fix:
Practice on VectorTyping's exam-specific passages that mirror the exact vocabulary and difficulty of official notifications.
04
Confusing CPM, KPH, and KDPH as different metrics
KPH (Keystrokes Per Hour) and KDPH (Key Depressions Per Hour) are the same thing. CPM × 60 = KDPH. Candidates sometimes think a job asking for "10,000 KPH" is harder than an exam requiring "10,000 KDPH" — they're identical requirements.
Fix:
KPH = KDPH = CPM × 60. Convert to WPM first, then compare across any spec or scorecard.
Common questions answered
Frequently Asked Questions
WPM, KDPH, and government exam typing standards — answered.
WPM (Words Per Minute) counts 5-character groups typed per minute. KDPH (Key Depressions Per Hour) counts every keystroke over an hour. SSC and most Indian government exams use KDPH because it measures raw keystroke output, not word boundaries. The conversion formula: KDPH = WPM × 5 × 60.
SSC CHSL LDC / JSA requires a minimum of 8,000 KDPH, which equals approximately 26.7 WPM. SSC CHSL DEO requires 15,000 KDPH, which equals 50 WPM. Always verify with the official SSC notification for the current year, as cutoffs can change.
Railway RRB NTPC requires 8,000 KDPH (approximately 26.7 WPM) for English and 25 WPM for Hindi. The test is qualifying — RRB measures speed, not accuracy deductions.
No. The 5-keystroke-per-word formula is the SSC standard and applies to most central government exams. Some state-level and court exams use a character-count formula where each character including spaces counts as one depression. Confirm with the official exam notification before assuming SSC rules apply.
CPM is Characters Per Minute, equivalent to keystrokes per minute. 1 WPM = 5 CPM by the SSC standard. CPM = WPM × 5. KDPH = CPM × 60. A typist at 35 WPM types 175 CPM and 10,500 KDPH.
Yes. The WPM ↔ KDPH formula applies to Hindi typing. Some exams measure Hindi speed using Devanagari character count per minute rather than the 5-keystroke formula. Check your specific exam notification for the method used.
Network latency, error penalty rules (half vs full mistakes), backspace restrictions, and harder passages all pull your score down on exam day. Build a 10–15% speed buffer above the cutoff to absorb them.
Accuracy comes before speed. Each error costs more time than it saves. Keep hands on the home row (ASDF / JKL;). Practice your weakest fingers with targeted drills. 20–30 minutes of focused daily practice beats occasional long sessions. VectorTyping's error pattern analysis shows which keys slow you down.
