E-CodeUnit converter: length, mass, volume, pressure, energy, power, temperature — a TI-84 Plus CE program
UNITCNV is a TI-BASIC program for the TI-84 Plus CE. Pick a quantity, then convert between metric and US units by number: length, mass, volume, pressure, energy, power and temperature (°C, °F, K, °R, refusing anything below absolute zero).
What it asks for and what it shows
It asks for 3 values at its prompts, after you pick option 1 from its menu. In the example below it shows IN, OUT.
Example run
One of its oracle test cases: “5 miles to km”. The inputs are typed in order, and the results are the values the case expects on the screen.
