Units To lays out speed units one to a row and amounts one to a column, so any amount reads in every unit at once: kilometres per hour, miles per hour, knots, metres per second, feet per second and minutes per kilometre, and for fun, garden snails, walking paces, Usain Bolts and cheetahs. Type an amount the way you would say it, lay out a range of amounts, and choose how many decimal places to show.
