Download e-book for iPad: Whatever Happened to the Metric System?: How America Kept by John Bemelmans Marciano

The yank normal approach of size is a special and extraordinary factor to behold with its esoteric, inconsistent criteria: twelve inches in a foot, 3 toes in a backyard, 16 oz. in a pound, 100 pennies to the greenback. For whatever as elemental as counting and estimating the area round us, it kind of feels like a complicated device to take advantage of.
