Hash Rate Converter
Instantly convert a mining hash rate between units such as H/s, KH/s, MH/s, GH/s, TH/s, and PH/s. Useful for comparing miner specs or interpreting pool statistics across different scales.
About this calculator
Hash rate measures how many cryptographic hash computations a miner performs per second. Each step up the unit ladder represents a factor of 1,000: 1 KH/s = 1,000 H/s, 1 MH/s = 1,000 KH/s, and so on. The conversion formula is: convertedValue = hashValue × 10^((fromUnit − toUnit) × 3). Here, fromUnit and toUnit are numeric indices representing the unit's position in the scale (e.g., 0 = H/s, 1 = KH/s, 2 = MH/s, 3 = GH/s, 4 = TH/s, 5 = PH/s). A positive exponent scales the value up; a negative exponent scales it down. This formula generalises all conversions to a single expression, avoiding the need for separate lookup tables. Understanding hash rate units is essential for evaluating mining hardware, comparing pool difficulties, and estimating electricity-to-reward ratios.
How to use
Suppose you want to convert 5,000 MH/s into GH/s. MH/s has index 2 and GH/s has index 3. Enter hashValue = 5,000, fromUnit = 2, toUnit = 3. The calculator computes: convertedValue = 5,000 × 10^((2 − 3) × 3) = 5,000 × 10^(−3) = 5,000 × 0.001 = 5 GH/s. So 5,000 MH/s equals exactly 5 GH/s. Conversely, converting 5 GH/s back to MH/s would give 5 × 10^((3−2)×3) = 5 × 1,000 = 5,000 MH/s, confirming the result.
Frequently asked questions
What is the difference between MH/s, GH/s, and TH/s in crypto mining?
MH/s (megahashes per second), GH/s (gigahashes per second), and TH/s (terahashes per second) are all units of mining hash rate, each 1,000 times larger than the previous. A GPU mining Ethereum Classic might operate at 30–100 MH/s, while an ASIC miner for Bitcoin typically runs at 50–200 TH/s — six orders of magnitude higher. Using the correct unit matters because quoting your miner's speed in the wrong unit can make it appear millions of times more or less powerful than it actually is.
How does hash rate affect cryptocurrency mining profitability?
Higher hash rate means your miner solves more puzzles per second, giving you a proportionally larger share of newly minted coins relative to the total network hash rate. However, as more miners join the network, the difficulty adjusts upward, reducing each miner's effective share even if their absolute hash rate stays constant. Profitability therefore depends on your hash rate relative to the entire network, your electricity cost per kilowatt-hour, and the current coin price — not on hash rate alone.
Why do different cryptocurrencies use different hash rate units?
Different coins use different hashing algorithms — Bitcoin uses SHA-256, Ethereum Classic uses Etchash, Litecoin uses Scrypt, and Monero uses RandomX, among others. Each algorithm has a different computational complexity, so the achievable hash rates differ enormously. Bitcoin ASIC miners reach petahash levels because SHA-256 is relatively simple for dedicated hardware, while Monero's RandomX is deliberately CPU-friendly and memory-hard, limiting typical miners to kilohashes or low megahashes. Quoting hash rate in an appropriate unit for each coin keeps the numbers human-readable rather than astronomically large or tiny.
