SI Prefixes
SI prefix converter from yocto to yotta. Convert between nano-, micro-, milli-, kilo- and mega- with a solution and a table.
⇄
A prefix works with any unit: 5 kilo (km, kg, kW) = 5000 units (m, g, W).
The SI prefix converter converts a value from one decimal prefix to another, for example from kilo- to milli-. A prefix multiplies the unit by a power of ten, so the result applies to meters, grams, watts and any other SI unit.
Units

| kilo-, 10³ (k) | 10³ |
| hecto-, 10² (h) | 10² |
| deca-, 10¹ (da) | 10¹ |
| no prefix (10⁰) (unit) | 10⁰ |
| deci-, 10⁻¹ (d) | 10⁻¹ |
| centi-, 10⁻² (c) | 10⁻² |
| milli-, 10⁻³ (m) | 10⁻³ |
| micro-, 10⁻⁶ (µ) | 10⁻⁶ |
| nano-, 10⁻⁹ (n) | 10⁻⁹ |
| pico-, 10⁻¹² (p) | 10⁻¹² |
| femto-, 10⁻¹⁵ (f) | 10⁻¹⁵ |
| atto-, 10⁻¹⁸ (a) | 10⁻¹⁸ |

| yocto-, 10⁻²⁴ (y) | 10⁻²⁴ |
Example. 5 kilo = 5 · 10³ = 5000 units: 5 km = 5000 m, 5 kW = 5000 W.
