Kilovolt in other electric potential (voltage) units
Kilovolt quick reference
| Kilovolt | Volt | Millivolt | Microvolt |
|---|---|---|---|
| 1 kV | = 1000 V | = 1000000 mV | = 1000000000 µV |
| 10 kV | = 10000 V | = 10000000 mV | = 10000000000 µV |
| 100 kV | = 100000 V | = 100000000 mV | = 100000000000 µV |
| 1000 kV | = 1000000 V | = 1000000000 mV | = 1000000000000 µV |
Where the kilovolt fits
The next smaller electric potential (voltage) unit is the statvolt (statV). 1 kV ≈ 3.335640952 statV, and 1 statV = 0.299792458 kV.
The next larger electric potential (voltage) unit is the megavolt (MV). 1 kV = 0.001 MV, and 1 MV = 1000 kV.
