Tera quick reference
| Tera | Giga | Kilo | Milli |
|---|---|---|---|
| 1 T | = 1000 G | = 1000000000 k | = 1e+15 m |
| 10 T | = 10000 G | = 10000000000 k | = 1e+16 m |
| 100 T | = 100000 G | = 100000000000 k | = 1e+17 m |
| 1000 T | = 1000000 G | = 1000000000000 k | = 1e+18 m |
Where the tera unit fits
The next smaller si prefixes unit is the giga unit (G). 1 T = 1000 G, and 1 G = 0.001 T.
The next larger si prefixes unit is the peta unit (P). 1 T = 0.001 P, and 1 P = 1000 T.
