Convert and Compare Mining Hash Rates
Hash rate is how many hash calculations a miner, pool or whole network performs each second. Spec sheets, pool dashboards and network statistics quote it in different units, from MH/s for a graphics card to EH/s for the Bitcoin network. This tool converts a hash rate into every unit from H/s to ZH/s, compares two hash rates, and lists the rated speeds of 13 common miners.
It doesn't estimate mining profit. Profit depends on live figures such as network difficulty, coin price, transaction fees and your electricity cost, which this tool doesn't fetch. The formula further down shows how to estimate your share of block rewards yourself.
How to Use the Hash Rate Calculator
- Unit Converter: type a value and choose its unit. The result updates as you type and shows the same rate in all eight units.
- Compare: enter two hash rates, in any units, to see how many times higher one is, the difference and the percentage.
- Hardware: pick a miner or GPU to load its rated hash rate into the converter. Filter by ASIC or GPU, or search by name.
- Copy a single value, or use Copy All for the full list.
Hash Rate Units
Hash rate units use decimal SI prefixes, so each unit is exactly 1,000 times the one before. 1 TH/s is 1,000 GH/s, not 1,024.
| Unit | Name | Hashes per second | Typically used for |
|---|---|---|---|
| H/s | hash per second | 1 | Base unit |
| KH/s | kilohash | 1,000 | Early CPU mining |
| MH/s | megahash | 1,000,000 | GPUs on Ethash-type algorithms; small Scrypt miners |
| GH/s | gigahash | 10⁹ | Scrypt ASICs such as the Antminer L7 |
| TH/s | terahash | 10¹² | Single Bitcoin (SHA-256) ASIC miners |
| PH/s | petahash | 10¹⁵ | Mining farms |
| EH/s | exahash | 10¹⁸ | Large pools and the Bitcoin network |
| ZH/s | zettahash | 10²¹ | Bitcoin network totals in recent years |
Worked Examples
Converting 100 TH/s
100 TH/s is 100,000 GH/s, 0.1 PH/s and 0.0001 EH/s. In hashes per second it's 100,000,000,000,000, or 10¹⁴.
Comparing two Bitcoin miners
Comparing an Antminer S19 XP (140 TH/s) with an Antminer S19 (95 TH/s): the S19 XP has 1.474× the hash rate, 45 TH/s more, which is 47.37% higher.
Energy efficiency (J/TH)
Hash rate alone doesn't show running cost. Divide power in watts by hash rate in TH/s to get joules per terahash; lower is better. Using the rated figures, the S19 XP uses 3,010 W ÷ 140 TH/s = 21.5 J/TH and the S19 uses 3,250 W ÷ 95 TH/s ≈ 34.2 J/TH. The calculator doesn't compute this for you, but the hardware list shows both numbers.
Estimating Your Share of Bitcoin Block Rewards
On average your share of rewards matches your share of the network's hash rate. Bitcoin aims for one block about every 10 minutes, roughly 144 a day, and the block subsidy has been 3.125 BTC since the April 2024 halving.
share = your hash rate ÷ network hash rate BTC per day ≈ share × 144 × 3.125For illustration, take a 100 TH/s miner and a network of 1,000 EH/s (1 ZH/s). Compare the two in this tool and the network is 10,000,000× larger, so the share is 1×10⁻⁷. That gives about 1×10⁻⁷ × 144 × 3.125 = 0.000045 BTC a day before fees. Mining alone, that miner would find a block on average once every 1 ÷ (1×10⁻⁷ × 144) ≈ 69,000 days, about 190 years. Pools exist to turn that into small, regular payouts.
Use the current network hash rate from a live source such as mempool.space; it changes daily. The estimate leaves out transaction fees, which add to rewards, and pool fees, downtime and difficulty changes, which affect what you actually receive.
Only Compare Hash Rates on the Same Algorithm
A hash rate counts hashes of one specific algorithm. Bitcoin uses SHA-256, Litecoin and Dogecoin use Scrypt, and Ethereum Classic uses Etchash. One Scrypt hash takes far more work than one SHA-256 hash, so 9.5 GH/s on a Scrypt miner and 140 TH/s on a SHA-256 miner can't be compared directly, even though the converter will happily put them in the same unit.
Ethereum itself no longer has a hash rate: it switched from mining to proof of stake in September 2022 (the Merge). The GPU figures in the hardware list are Ethash rates, which remain a common way to compare graphics cards and roughly match Ethereum Classic's Etchash.
About the Hardware Figures
- ASIC hash rates and power are the manufacturers' stock ratings. Units vary, and firmware, temperature and tuning change real results.
- GPU hash rates are commonly reported Ethash figures with tuned memory clocks. The wattage shown is the card's rated board power, not a measured mining draw, which is usually lower after tuning.
- The list is fixed and covers popular models rather than the newest releases. Check the manufacturer's current specifications before buying.

Frequently Asked Questions
How many GH/s are in a TH/s?
1,000. Likewise 1 GH/s = 1,000 MH/s and 1 PH/s = 1,000 TH/s.
How do I convert MH/s to TH/s?
Divide by 1,000,000. For example, 500 MH/s is 0.0005 TH/s.
Is a higher hash rate always better?
Within the same algorithm, a higher hash rate means more work done per second, but profit also depends on power use. A miner with a lower hash rate can cost less to run per terahash, so compare J/TH as well.
Can I mine Bitcoin with a GPU?
Technically yes, but a graphics card's SHA-256 rate is a tiny fraction of a single ASIC's, so its share of the network is negligible. Bitcoin mining is done with SHA-256 ASICs.
What does the calculator's percentage mean?
It's how much higher the larger hash rate is than the smaller one. 140 TH/s is 47.37% higher than 95 TH/s; put the other way round, 95 TH/s is about 32% lower than 140 TH/s.
