Summary Example-1 Metric Conversions 0.47 km (kilometer) = 470 m When converting from a larger unit to a smaller unit, move the decimal point to the right. Remember, a smaller unit means the number must be larger. 0.47 km (kilometer) = 470 m 1.7 m = 1700000 μm Example-1

Summary Example-2 Metric Conversions 10,000 pm = 0.01 mm = 0.00001 mm When converting from a smaller unit to a larger unit, move the decimal point to the left. Remember, a larger unit means the number must be smaller. 10,000 pm = 0.01 mm = 0.00001 mm Example-2

Summary Example-1 Metric Arithmetic 10,000 g + 22 kg = When adding or subtracting numbers with a metric prefix, convert them to the same prefix first. Example-1 10,000 g + 22 kg = 10,000 g + 22,000 g = 32,000 g Alternatively, 10 kg + 22 kg = 32 kg

Summary Example-2 Metric Arithmetic 200 μg + 1.0 mg = When adding or subtracting numbers with a metric prefix, convert them to the same prefix first. Example-2 200 μg + 1.0 mg = 200 mg + 1,000 mg = 1,200 mg Alternatively, 0.200 mg + 1.0 mg = 1.2 mg
