Gigaohm in other electric resistance units
Gigaohm quick reference
| Gigaohm | Ohm | Kiloohm | Microohm |
|---|---|---|---|
| 1 GΩ | = 1000000000 Ω | = 1000000 kΩ | = 1e+15 µΩ |
| 10 GΩ | = 10000000000 Ω | = 10000000 kΩ | = 1e+16 µΩ |
| 100 GΩ | = 100000000000 Ω | = 100000000 kΩ | = 1e+17 µΩ |
| 1000 GΩ | = 1000000000000 Ω | = 1000000000 kΩ | = 1e+18 µΩ |
Where the gigaohm fits
The next smaller electric resistance unit is the megaohm (MΩ). 1 GΩ = 1000 MΩ, and 1 MΩ = 0.001 GΩ.
The next larger electric resistance unit is the statohm (statΩ). 1 GΩ ≈ 0.001112650056 statΩ, and 1 statΩ = 898.75517873681764 GΩ.
