How it works
- Enter a value and choose the input prefix, and the value for every prefix from pico to peta is listed in the table.
- Each prefix is converted with the exact powers-of-ten factor it is defined by (e.g. kilo = 10^3, milli = 10^-3).
- The no-prefix (×1) base value is shown large at the top, and the current input prefix is highlighted in the table.
- Very large or very small results are shown in scientific notation (e.g. 1.2300e+9) for readability.
- Useful for science and physics unit work, and for understanding everyday prefixed units such as deciliter or hectopascal.
