Conversion method
Electric field is force per charge, equivalently potential gradient. V/m and N/C are equivalent units.
kV/m = x × 0.001
10 V/m = 0.01 kV/m.
| V/m | kV/m |
|---|---|
| 1 | 0.001 |
| 5 | 0.005 |
| 10 | 0.01 |
| 25 | 0.025 |
| 50 | 0.05 |
| 100 | 0.1 |

Precision of electric field strength conversions
All 10 electric field strength units convert through Volt per meter (V/m). 10 have an exact defined relationship to the base unit and 0 are conventional or measured values. Results and the tables on this page come from the same engine, so a table value can be checked against the converter directly.
Standard display shows up to six decimal places, switching to scientific notation for very large or small values. Calculation uses JavaScript binary floating point independently of display rounding, so extra digits are not a claim about measurement accuracy. Each unit lists its own source; a citation records where the definition comes from, not an independent review. See Conversion methodology for the review and correction process.
