There are two common ways to measure how many kilobytes (KB) are in a gigabyte (GB), depending on whether you use the decimal (base 10) or binary (base 2) system:
- Decimal system (SI units):
1 GB = 1,000,000 KB
This is based on 1 kilobyte = 1,000 bytes and 1 gigabyte = 1,000,000,000 bytes, commonly used in storage device marketing and general data sizes
- Binary system (used by many operating systems):
1 GB = 1,048,576 KB
This comes from 1 kilobyte = 1,024 bytes and 1 gigabyte = 1,073,741,824 bytes (1024³ bytes), often used in computer memory and OS calculations
In summary:
Measurement System| Kilobytes in 1 Gigabyte
---|---
Decimal (SI)| 1,000,000 KB
Binary| 1,048,576 KB
Both values are correct depending on context, but the binary value is typically used in computing environments, while the decimal value is used in storage device specifications.
