Wire Gauge Formula

Use our AWG wire diameter formula to find the wire gauge length. To find the gauge of the cable, first step is to calculate the log for the given diameter value. Then multiply the obtained value with 20. Finally, subtract the resultant value with -10. The gauge value helps in computing the essential electric power supply to be transmitted and also determines the electrical resistance. You can manually compute the length of wire here in this wire gauge formula.
