Unit conversions

This provides a number of unit conversion options for distance, mass, area, pressure, temperature, rate time units, energy, water loss, light intensity. It is similar to (but more comprehensive than) many of the options in the 'transformations' routines in the EDIT menu. You need to select a general type of conversion from four choices, then pick the specific conversion from the pop-up menu. For some conversion, text describing special conditions will appear.
