From a bigger unit to a smaller one, multiply: 1 km = 1,000 m, so 6.3 km = 6,300 m. From smaller to bigger, divide: 240 g = 0.24 kg.
Watch for: Dividing when going to a smaller unit, so 6.3 km comes out as 0.0063 m. Using 100 for every metric change: km to m is 1,000, but m to cm is 100. Using 10 for customary units: 1 foot is 12 inches and 1 pound is 16 ounces.
At home: Read labels together: a 2 L bottle is how many mL? A 500 g box is how many kg? Say each answer with its unit.
