H/s or hash rate is the speed at which mining equipment performs calculations. In the context of cryptocurrencies, this parameter demonstrates the efficiency of video cards and asics. It is important to understand what KH/s and GH/s are in mining. They are directly related to profitability – the higher these parameters are in the equipment, the more likely it is to get a reward for creating a block.
What H/s means in mining
H/s is the hash rate, which is understood as:
- The total processing power of the blockchain.
- The amount of hash produced by the hardware per second.
Miners are interested in 2 indicators at once, since the profitability of cryptocurrency mining depends on both. The capacity of the Bitcoin network as of February 15, 2023 is 304,445 EH/s. This is the total amount of mining equipment connected to the network. Due to the Proof-of-Work consensus feature, the one who is faster at computing and creating a new block will get the revenue.
The sheer power of the network has made mining on home PCs impossible. A single video card with 22-31 Mh/s does not have time to solve the ever-complicated crypto tasks. Accordingly, the user must increase the power or switch to another currency.
A high hash rate makes mining BTC and other coins more difficult, but at the same time it is considered an indicator of network stability. David Kemmerer, co-founder of CoinLedger, said:
“Blockchains need computers to process and verify transfers. The more devices competing to control transactions by trying to guess the next hash, the safer the network becomes. Thus, the higher the hash rate for a given blockchain being validated, the more secure it is against attacks.”

Those planning to invest in cryptocurrency need to consider hash rate. The more computers around the world verifying transactions, the more difficult it is for a 51% attack to manipulate transactions and create fake blocks.
From this perspective, Bitcoin is considered the most secure crypto coin. It would take more than one warehouse of computers to take over 51% of the network. For example, investors of the less secure Verge blockchain lost $1.4 million in 2018 due to a hack. Bitcoin SV also fell victim to an attack in 2021.
How to calculate the hashrate of a specific hardware
If a mining farm is connected and working, its efficiency can be found out in the following coin mining programs:
- Nice Hash Miner
- ZCash – EWBF’s CUDA Zcash miner.
The console will show the hashrate of all the hardware at once or of each video card separately. It depends on the application settings.
If the device has not yet been purchased, then you can find out the speed on sites such as:
- What to Mine – popular Asic and GPU are collected.
- Hashrate.no – shows the maximum hardware speed for different blockchains.
In the case of asics sharpened for cryptocurrency mining, hashrate is indicated on the manufacturer’s website.
Difference between KH/s, GH/s and TH/s in mining
The hash rate is measured in hashes per second – H/s, but due to the increasing computing power of blockchains, they started adding prefixes such as mega, giga, tera, peta, exa, zetta. Therefore, KH/s and GH/s in mining are relatively small numbers. As of February 15, 2023, Bitcoin includes 304445 petahesh.
Below is a table with the full list of units and names.
| Name | Designation | Number of hashes per second |
|---|---|---|
Hash rate
This parameter denotes the processing power of the hardware used to solve cryptographic problems. Miners who mine blockchain coins with PoW need to regularly increase the hash rate of the farm.
It is worth noting that the rate does not apply to Proof-of-Stake blockchains. To make money from them, you don’t need a farm with a high hash rate.
Conversions
By H/s it is impossible to determine the profitability of mining, since the income is affected not only by the hash rate, but also by electricity costs, the cost of digital currency on the exchange. To calculate the conversion, calculators are used:
You need to select a video card or farm configuration, cryptocurrency and enter the electricity costs. After a minute, the user will see the yield.
Frequently Asked Questions
📢 How to mine cryptocurrencies with high hash rate?
For those who want to get BTC, not obscure koins, even a powerful farm is not enough. It is more profitable to invest in mining pools, for example: Binance Pool, ViaBTC, Trustpool, which share the total reward among contributors.
⚡ How are H/s distributed in the blockchain?
In the case of popular coins, there is a centralization of power around mining pools. Huobi, AntPool, F2Pool, Poolin are the most heavily weighted.
📌 What does hash rate depend on?
It is influenced by the characteristics of the graphics card, connection method, chip temperature, operating system, timing of command execution.
🔥 What is more profitable: ASIC or graphics card?
ASICs are customized for cryptographic tasks and are more powerful than even the latest NVIDIA developments.
✨ Can I overclock my mining cards?
Yes. This way you can increase the power of devices by 10-14%. The main thing is to monitor the temperature and reduce power consumption with Core Clock, Core Voltage.
