4. 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 = μm
Example-1

5. 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 = mm
Example-2

6. 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

7. 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 mg =
200 mg + 1,000 mg = 1,200 mg
Alternatively,
0.200 mg mg = 1.2 mg
