Microvolt in other electric potential (voltage) units
Microvolt quick reference
| Microvolt | Millivolt | Volt | Kilovolt |
|---|---|---|---|
| 1 µV | = 0.001 mV | = 0.000001 V | = 1e-9 kV |
| 10 µV | = 0.01 mV | = 0.00001 V | = 1e-8 kV |
| 100 µV | = 0.1 mV | = 0.0001 V | = 1e-7 kV |
| 1000 µV | = 1 mV | = 0.001 V | = 0.000001 kV |
Where the microvolt fits
The next smaller electric potential (voltage) unit is the abvolt (abV). 1 µV = 100 abV, and 1 abV = 0.01 µV.
The next larger electric potential (voltage) unit is the millivolt (mV). 1 µV = 0.001 mV, and 1 mV = 1000 µV.
