These are simple mortar ranging calculators that use linear interpolation to estimate firing solutions.

The Manual Calculator lets you input two known range-to-mil pairs and their corresponding D-ELEV values. It’s primarily for use with non-standard mortars (i.e., not the default American or Soviet ones).
For example, if your mortar table shows 240m at 600 mils and 300m at 400 mils, and you want to find the mil value for 270m, this calculator handles that with ease.
If your table doesn't provide D-ELEV (mils per 100m drop), just enter 0.

The Standard Calculator is more straightforward and works automatically with supported mortar types.
