Units To lays out acceleration units one to a row and amounts one to a column. Opened at metres per second squared, it reads any amount of them at once in feet per second squared, standard gravities, gals, kilometres per hour per second, miles per hour per second and every other acceleration unit, even cheetahs and Space Shuttles. Type an amount the way you would say it, lay out a range of amounts, and choose how many decimal places to show.
