Hash rate is how fast a mining machine tries answers to the puzzle that secures a blockchain.
The units
| Unit | Meaning | Hashes per second |
|---|---|---|
| H/s | hash | 1 |
| KH/s | kilohash | 1,000 |
| MH/s | megahash | 1,000,000 |
| GH/s | gigahash | 1,000,000,000 |
| TH/s | terahash | 10^12 |
| PH/s | petahash | 10^15 |
| EH/s | exahash | 10^18 |
Why it matters
More hash rate means more chances to find the next block, but the network adjusts difficulty so blocks arrive at a steady pace. See how Bitcoin mining works.
Hash rate in apps
A phone’s real processor produces a tiny number compared with specialised machines. An app showing “100 TH/s” on your phone is displaying a made-up figure. Treat it as a game element. Read what mining simulator apps are and the scam red flags.
