Know relative sizes of measurement units within one system of units including km, m, cm; kg, g; lb, oz.; l, ml; hr, min, sec. Within a single system of measurement, express measurements in a larger unit in terms of a smaller unit. Record measurement equivalents in a two-column table. For example, know that 1 ft. is 12 times as long as 1 in. and that 4 ft. is equal to 48 in. Generate a conversion table for feet and inches listing the number pairs (1, 12), (2, 24), (3, 36), and so on.
