Volt per Meter (V/m) is used as the internal base unit. Every value you enter is first converted to Volt per Meter using exact SI factors, then translated to the requested unit with the same data pulled from the SI Brochure and NIST SP 811.

Key electric field strength relationships

1 Kilovolt per Meter = 1,000 Volt per Meter
1 Volt per Centimeter = 100 Volt per Meter
1 Volt per Millimeter = 1,000 Volt per Meter
1 Volt per Inch = 39.3701 Volt per Meter
1 Volt per Foot = 3.28084 Volt per Meter

Where electric field strength units are used

Electrical engineers, PCB designers, and maintenance teams convert these electrical quantities while specifying circuits, troubleshooting faults, and documenting test data. The electric field strength converter covers real-world units such as Volt per Meter and Kilovolt per Meter, giving teams a trusted reference when cross-checking data between labs, suppliers, and regulatory filings.

Tips for accurate electric field strength conversions

Always verify the unit symbol in your worksheet—this converter normalizes values through Volt per Meter, which is the SI reference for electric field strength measurements.
When jumping between Volt per Meter and Kilovolt per Meter, watch metric prefixes and rounding. A misplaced milli-, micro-, or kilo- prefix can produce errors of several orders of magnitude.
Document the context (test conditions, instrument resolution, uncertainty) whenever you publish electric field strength conversions so coworkers and auditors can reproduce your results.
