Units To lays out flow rate units one to a row and amounts one to a column, so any amount reads in every unit at once: litres per minute, US gallons per minute, cubic metres per hour, cubic feet per minute, millilitres per hour and litres per hour, and, just to be silly, kitchen taps, Niagara Falls and Amazons. Type an amount the way you would say it, lay out a range of amounts, and choose how many decimal places to show.
