The Rock Climbing Calc provides some useful formulas for rock climbing and Height as a function of time to drop.other activities related to scaling and measuring heights.
This calculator provides some simple computations for estimating the height of an elevation (cliff, bridge, building). The two methods are base on:
The latter is more accurate but requires a devices to measure the angles and the distances between the observation. A protractor and weighted string can be used to measure the angles, and a standard tape-measure can be used to compute the distance between observations. The first method only requires a stop watch.
