Spherical or ellipsoidal earth?
Spherical, using the mean radius. The error against a proper ellipsoidal calculation is around a tenth of a percent, which is well under a metre over any tactical distance and a few metres across a state.
Can I enter grid references instead?
Not on this page. Use the coordinate converter to get lat and long first, then bring them here.
