How to use it
- Type a number. A dot or a comma works as the decimal separator.
- Choose the unit you have and the unit you need.
- The table shows the same value in all common units at once.
Conversion factors
Every unit is converted through volts per metre (V/m).
| Unit | In V/m |
|---|---|
| 1 V/cm | 100 |
| 1 V/mm | 1,000 |
| 1 kV/cm | 100,000 |
| 1 MV/m = 1 kV/mm | 1,000,000 |
| 1 V/in | ≈ 39.37 |
| 1 statV/cm | 29,979.2458 |
Worked example
An insulator is rated for 3 kV/mm. That is 3 × 1,000,000 = 3 MV/m, or 30 kV/cm. Across a 2 mm gap it holds up to 3 × 2 = 6 kV.
Quick reference
- 1 V/m = 1 N/C
- E = V / d for a uniform field between plates
- Field strength is a vector; this tool converts only its size
