Conversion of units
Required
Proper conversion
Solution
In converting units we must pay attention to the conversion factor between units
Let kg to g, then the conversion factor is 10³
1. L to mL = 10³
2000 L to ml = 2.10⁶ ml
wrong conversion
2. cm to mm = 10
5.25 cm = 52.5 mm
wrong conversion
3. mg to g = 10⁻³
35 mg = 35 x 10⁻³ g = 3.5 x 10⁻⁴ g
wrong conversion
4. km to mm = 10⁶
6 km = 6 x 10⁶ mm
proper conversion
