Metric and Conversions Practice—ANSWER KEY
Honors
1. Order the following prefixes from smallest to largest: nano/centi/milli/kilo/Giga/Mega/deci
nano/milli/centi/deci/kilo/Mega/Giga
2. What is the value of the following prefixes? nano/centi/milli/kilo/Giga/Mega/deci
nano = billionth
centi = hundredth
milli = thousandth
kilo = 1000
Giga = billion
Mega = million
deci = tenth
3. What are the standard units for measuring length, mass and time? Meters, kilograms, seconds
4. Convert the following
a) 30 kg to cg
30 Kg x (1000 g/1kg) x (100 cg/1 g) = 3,000,000 cg
b) 100 km to mm
100 km x (1000 m/1 km) x (1000 mm/1 m) = 100,000,000 mm
c) 150 ns to seconds
150 ns x (1s/1,000,000,000 ns) = 1.5 x 10-7 seconds
5. How many feet are in 6 km?
6 km x (1000 m/1 km) x (100 cm/1 m) x (1 in/2.54 cm) x (1 ft/12 in) = 19,685 feet
6. Convert 70 mi/hr to (a) m/s and (b) km/hr
70 mi/hr x (1 hr/3600 s) x (1609 m/1 mi) = 31.3 m/s
70 mi/hr x (1609 m/1 mi) x (1 km/1000 m) = 112.6 km/hr
