Use dimensional analysis for all these problems. Showing a sequence of connected unit
fractions is important. These will require converting between systems (US and Metric).
The units you need to convert between systems are in the middle column.
12 inches (in) = 1 foot (ft)
2.54 centimeters (cm) = 1 inch (in)
3 feet (ft) = 1 yard (yd)
1 kilometer (km) = 0.62 miles (mi)
1760 yards (yd) = 1 mile (mi)
5280 feet (ft) = 1 mile (mi)
9. Convert 1.5 kilometers to feet.
10. Convert 1.5 miles to meters.
11. Convert your height to centimeters.
1000 millimeters (mm) = 1 meter (m)
1000 meters (m) = 1 kilometer (km)
100 centimeters (cm) = 1 meter (m)
