- DMS to Decimal Degrees Converter (and DDM)Convert coordinates between degrees-minutes-seconds, degrees and decimal minutes and decimal degrees, in every direction, for latitude and longitude — and see what each decimal place is actually worth in metres at your own latitude, computed on the WGS 84 ellipsoid.
- Slope and Grade Converter (%, Degrees, 1:12, Roof Pitch)Convert a slope between per cent grade, degrees, a 1 in n ratio, millimetres per metre, inches per foot and roof pitch in twelfths, in every direction — with the published limits that make the number mean something: the ADA's ramp rules, the IRC's minimum roof slopes and two countries' drainage falls.
