KH/s vs. MH/s: Hash Rate Difference Explained
KH/s (kilohash per second) means 1,000 hashes per second; MH/s (megahash per second) equals 1,000,000. Hash rate is the speed a mining chip guesses crypto solutions.
Beginners eyeball miner profit calculators and see “1,000 KH/s” next to “1 MH/s,” assume both are equal, and panic when payouts differ—hence the daily mix-up on Reddit and Discord.
Key Differences
KH/s fits small GPUs or CPUs mining coins like Monero. MH/s is the realm of ASICs or high-end GPUs chasing Ethereum Classic. The gap is three orders of magnitude: 1 MH/s = 1,000 KH/s.
Which One Should You Choose?
Match hardware to coin. If your rig tops out under 1 MH/s, stick to networks still priced in KH/s. Otherwise, aim for MH/s tiers to keep electricity from eating your margin.
Can I convert KH/s directly into dollars?
No; you need the coin’s difficulty, price, and your power cost—hash rate alone only tells guessing speed.
Why do some pools list GH/s instead?
GH/s is 1,000 MH/s; large farms aggregate so much power that smaller units become messy to read.
Does higher hash rate guarantee more coins?
Only if network difficulty and coin price stay constant—both rarely do.
