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

Key current relationships

1 Kiloampere = 1,000 Ampere
1 Megaampere = 1.0000e+6 Ampere
1 Gigaampere = 1.0000e+9 Ampere
1 Milliampere = 0.001 Ampere
1 Microampere = 1.0000e-6 Ampere

Where current units are used

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

Tips for accurate current conversions

Always verify the unit symbol in your worksheet—this converter normalizes values through Ampere, which is the SI reference for current measurements.
When jumping between Ampere and Kiloampere, 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 current conversions so coworkers and auditors can reproduce your results.
