Centi quick reference
| Centi | Kilo | Milli | Quetta |
|---|---|---|---|
| 1 c | = 0.00001 k | = 10 m | = 1e-32 Q |
| 10 c | = 0.0001 k | = 100 m | = 1e-31 Q |
| 100 c | = 0.001 k | = 1000 m | = 1e-30 Q |
| 1000 c | = 0.01 k | = 10000 m | = 1e-29 Q |
Where the centi unit fits
The next smaller si prefixes unit is the milli unit (m). 1 c = 10 m, and 1 m = 0.1 c.
The next larger si prefixes unit is the deci unit (d). 1 c = 0.1 d, and 1 d = 10 c.
