This is a simple tool to calculate appropriate resistor values for voltage dividers. Enter the desired reduction factor above and select the resistor series.

Common noations such as 1/8 or 1:4 for the ratio and 4k7 or 1m2 for the resistance are supported.

This tool uses Flask and Daniel Fairheads simple eval script.
