Convert between kilo, milli, mega, micro, and more.
Free to use, no sign-up required. Metric Prefix Converter is one of 198 tools built into Xenition, alongside a chat that can use them for you.
Converts a value between SI metric prefixes, from pico to tera, such as milliamps to amps or megabytes to gigabytes.
Each prefix is a power of ten: pico 10⁻¹², nano 10⁻⁹, micro 10⁻⁶, milli 10⁻³, centi 10⁻², base 1, kilo 10³, mega 10⁶, giga 10⁹, tera 10¹². The result is value × from factor ÷ to factor. Results below 0.000001 or at or above 10¹⁵ are shown in scientific notation.
1 kilo is 1,000 base units. 2.5 mega is 0.0025 giga. 4,700 pico, as in a 4,700 pF capacitor, is 4.7 nano.
The SI prefix kilo always means 1,000, and that is what this tool uses. The 1,024-based units have their own names, kibi, mebi and gibi (KiB, MiB, GiB).
A factor of 1,000. Each of the main prefixes from pico to tera is 1,000 times the one before, with centi as the one exception in between.
Metric Prefix Converter converts between 10 units: pico, nano, micro, milli, centi, base, kilo, mega, giga and tera. Factors are given against base.

| 1 micro | 0.000001 base | 1000000 micro |
| 1 milli | 0.001 base | 1000 milli |
| 1 centi | 0.01 base | 100 centi |
| 1 kilo | 1000 base | 0.001 kilo |
| 1 mega | 1000000 base | 0.000001 mega |
| 1 giga | 1000000000 base | 0.000000001 giga |
| 1 tera | 1000000000000 base | 0.000000000001 tera |
Common quantities in base, converted. Every value is computed from the factors above, so the chart and the converter cannot disagree.

1 base is 1000000000000 pico. To convert base to pico, divide by 0.000000000001 — so 10 base is 10000000000000 pico.
1 pico is 0.000000000001 base. To convert pico to base, multiply by 0.000000000001 — so 10 pico is 0.00000000001 base.
1 base is 999999999.9999998808 nano. To convert base to nano, divide by 0.000000001 — so 10 base is 10000000000 nano.
1 nano is 0.000000001 base. To convert nano to base, multiply by 0.000000001 — so 10 nano is 0.00000001 base.
1 base is 1000000 micro. To convert base to micro, divide by 0.000001 — so 10 base is 10000000 micro.
1 micro is 0.000001 base. To convert micro to base, multiply by 0.000001 — so 10 micro is 0.00001 base.
1 base is 1000 milli. To convert base to milli, divide by 0.001 — so 10 base is 10000 milli.
1 milli is 0.001 base. To convert milli to base, multiply by 0.001 — so 10 milli is 0.01 base.
You do not have to open Metric Prefix Converter to use it. Ask Xenition in plain language and it runs the right tool, then carries the answer into whatever you are working on — a document, a spreadsheet, a deck.
