Significant digits

Calculations use exact ratios internally; the displayed result is rounded to the selected significant digits. Input allows up to 30 digits and exponents from −30 to +30. Use a decimal point, decimal comma, or Arabic decimal separator; do not use thousands separators. Negative values are accepted only for valid temperatures.

How to use this tool

Enter a value, select the source and target units, and convert. Results also update while you type. Swap units keeps the entered value. Common examples fill the calculator for you. Copy copies the numeric result only.

Good to know

1 byte = 8 bits. Decimal kB, MB and GB use powers of 1,000; binary KiB, MiB and GiB use powers of 1,024. For example, 1 MiB = 1,048,576 bytes. Fractional results are mathematical quantities, not a filesystem allocation estimate.
