Mega quick reference
| Mega | Giga | Kilo | Base unit (no prefix) |
|---|---|---|---|
| 1 M | = 0.001 G | = 1000 k | = 1000000 ×1 |
| 10 M | = 0.01 G | = 10000 k | = 10000000 ×1 |
| 100 M | = 0.1 G | = 100000 k | = 100000000 ×1 |
| 1000 M | = 1 G | = 1000000 k | = 1000000000 ×1 |
Where the mega unit fits
The next smaller si prefixes unit is the kilo unit (k). 1 M = 1000 k, and 1 k = 0.001 M.
The next larger si prefixes unit is the giga unit (G). 1 M = 0.001 G, and 1 G = 1000 M.
