Description:
The units of the left hand side of any equation must always match those of the right hand side.
Anyone who has performed a derivation of reasonable complexity has probably managed to lose a dimension or two along the way, arriving at the end only to find that the units no longer match.
Walking back through the derivation to find the error is a tedious and time-consuming exercise.
This tool is designed to avoid having to do so by computing the exponents of the fundamental units, M, L, T and t.
