This Electronics design utility finds resistor pairs (E24 series) which, when paralleled together, give your target resistance value.

If this is not for you - here is a calculator which just calculates the equivalent resistance of two or three resistors connected in parallel.

Notes

The uses for this utility lie mainly within the area of electronics design, where accurate resistor values are needed, such as in the design of active filters, synthesizers, etc. This utility was written by the author whilst making audio crossover cards for large soundsystems, invariably not having the correct resistor values in stock. Reverse engineering resistor pairs by hand is tedious and time consuming even with a pocket calculator.
