# What is KH/s, MH/s, and GH/s? and Differences

Kilo Hash Power/second — KH/s
Mega Hash power/second — MH/s
Giga Hash power/second — GH/s

All these Hash powers are used for the calculation of cryptocurrency namely we know Bitcoin majorly famous digital cash.

Before jumping into topic let’s have a Glimpse of the terms we use and what are they.

### What is Hash rate?

In simple terms, a hash rate can be defined as the speed at which a given mining machine operates. Crypto mining involves finding blocks through complex computations. The blocks are like mathematical puzzles. The mining machine must make thousands or even millions of guesses per second to find the right answers to solve the block.

### Differences of Hash Powers and the measuring system

All these units such as kH/s, Mh/s, GHs and so on are the common terms used in the crypto mining operation. It is a speed at which a given mining hardware solves a problem. All these are called Hash rate and is computed as Hashes generated per second (H/s). Hash rate denominations are measured in standard metric prefixes just like how mass, volume, length and time are expressed.

KH/s = 1 000 Hashes/s
MH/s= 1 000 000 Hashes/s
GH/s = 1 000 000 000 Hashes/s
