Reference

How electric resistance conversion works

Electrical resistance describes opposition to current. Decimal SI prefixes cover the values most often used in electronics, power systems, and insulation measurements.

Values are converted to ohm first, then from that reference into the requested unit. Keeping a single documented reference reduces inconsistent pair-by-pair constants.

Accuracy note: SI prefix relationships and the abohm relationship are exact.
