# Relative armour thickness calculator

### Calculation of combined angle

This will calculate the combined angle of two angles, e.g. is an armor plate has both a lateral and vertical angle. 0° should be horizontal for the vertical slope and an armour plate facing the direction it is observed from (i.e. without any "twist") for the lateral slope.

### Armour thickness calculator

This will calculate the relative armour thickness at a given angle and actual plate thickness.
