💽 Byte Conversion Calculator
Convert any data size across bits, bytes, KB, MB, GB, and TB.
Select the starting unit, enter the value, and choose the target unit. The converter also shows quick references to other storage units so you can copy exactly what you need.
Enter a non-negative number. Decimals are supported.

How to Use This Calculator
Enter the value
Type the data amount you want to convert. Supports decimals and large values.
Choose source and target units
Select from bits, bytes, kilobytes, megabytes, gigabytes, and terabytes.
Copy the results
Use the main conversion or the quick references for documentation, system sizing, or bandwidth calculations.
Formula
Bytes = Value × (bytes per unit)
Converted Value = Bytes ÷ (bytes per target unit)
IEC (power-of-two) units use 1024 instead of 1000. This calculator uses SI (10³) prefixes unless otherwise noted.
Use the formula breakdown to confirm the calculation logic or perform the conversion manually if needed.
Full Description
Storage manufacturers, cloud providers, and networking equipment often use different data size conventions. This calculator standardizes conversions across SI units (10³) so you can compare specifications or size files quickly.
Whether you’re predicting backup sizes, estimating bandwidth requirements, or preparing training materials, the quick reference cards save time and reduce manual errors.
If you need binary (IEC) units such as MiB or GiB, note the difference and adjust the multiplier manually.
Frequently Asked Questions
Does it use SI or binary (IEC) prefixes?
This calculator uses SI prefixes (1 KB = 1000 bytes). For 1 KiB = 1024 bytes, multiply by 1024 manually or use a dedicated IEC converter.
Can I convert between bits and bytes?
Yes. Select bits as the source or target unit to convert instantly between bits and any other unit.
How large a number can I enter?
The calculator handles values within JavaScript’s number limits (up to around 9e15 for exact integers). For extremely large values, use high-precision tools.
Are negative values allowed?
No. Data sizes are typically non-negative. If you enter a negative value, a validation message appears.
