MH/s vs. GH/s: Hashrate Units Explained for Crypto Miners
MH/s equals one million hashes per second; GH/s is one billion. They are metric prefixes applied to hash-rate, the speed at which a mining rig solves cryptographic puzzles.
Miners read “1000 MH/s” on one pool dashboard and “1 GH/s” on another, then panic that profits vanished. The numbers look wildly different, yet mean the same work—so the confusion starts.
Key Differences
MH/s and GH/s differ only by a factor of 1,000. A 3,000 MH/s rig reports as 3 GH/s elsewhere, but the actual performance stays identical; the unit is just scaled up for cleaner reading.
Which One Should You Choose?
Use MH/s when quoting GPUs or small ASICs; switch to GH/s for high-output farms. Pools auto-display the scale that fits the network, so choose the label that keeps numbers short and readable.
Examples and Daily Life
Your RTX 3070 mines at 60 MH/s, while an Antminer S19 hits 110 TH/s (110,000 GH/s). A coffee break later, your pool dashboard flips from 0.06 GH/s solo to 60 MH/s merged—same earnings, no panic needed.
Is higher GH/s always more profitable?
No—profit hinges on efficiency (watts per hash) and electricity cost, not the unit label.
Can I convert MH/s to GH/s on any calculator?
Yes, divide by 1,000; no special crypto math required.
