Electric Field Strength Converter
Electric field strength is the force an electric field exerts on each unit of charge. The SI unit is the volt per metre (V/m), which is equivalent to newtons per coulomb.
1 Volt/Meter = 0.001 Volt/Millimeter
How to convert Volt/Meter to Volt/Millimeter
One Volt/Meter equals 0.001 Volt/Millimeter, so multiply any value in V/m by 0.001 to get V/mm. To convert back, divide by 0.001 — or multiply by 1,000.
V/mm = V/m × 0.001
Example: 25 V/m × 0.001 = 0.025 V/mm.
