Milli quick reference
| Milli | Kilo | Micro | Base unit (no prefix) |
|---|---|---|---|
| 1 m | = 0.000001 k | = 1000 µ | = 0.001 ×1 |
| 10 m | = 0.00001 k | = 10000 µ | = 0.01 ×1 |
| 100 m | = 0.0001 k | = 100000 µ | = 0.1 ×1 |
| 1000 m | = 0.001 k | = 1000000 µ | = 1 ×1 |
Where the milli unit fits
The next smaller si prefixes unit is the micro unit (µ). 1 m = 1000 µ, and 1 µ = 0.001 m.
The next larger si prefixes unit is the centi unit (c). 1 m = 0.1 c, and 1 c = 10 m.
