Standard Resistor Value Calculator: 1%, 5%, 10%

This calculator will select the closest standard resistor value, from 1% 5% or 10% standard EIA values, calculates the error, and prints out a table of the standard values for the given tolerance.

Resistor Value (Ohms)
Tolerance (%)	1% 5% 10%
Calculate

EIA Number	Tolerance
E12	10%
E24	5%
E96	1%

The EIA E number is the number of logarithmic steps. For example, for E12 has twelve steps between any power.
