For building measurements written as feet and inch fractions, calculate with feet, inches and tape-measure fractions; this is a measurement-arithmetic task in addition to unit conversion. If the converted dimensions describe engine cylinders, calculate engine displacement from bore, stroke and cylinder count; a volume-unit conversion alone does not calculate engine geometry.

RockUtility includes common measurements such as feet, miles, pounds, gallons, Celsius, Fahrenheit, square feet, acres, miles per hour, PSI, watts and gigabytes.

It also includes less common units such as nautical miles, furlongs, chains, rods, fathoms, leagues, hands, slugs, grains, barns, knots, Mach, astronomical units, parsecs and light-years.
