Use the sentence above about King Henry to remember the order of metric units! It will
also help you convert from one unit to another!
For example, 2.5 km = _____ m?
Start at K (king).
‘m’ stands for meter so count the number of spaces from K to m (base unit). (There
are 3 spaces from K to m.)
Move the decimal 3 spaces to the right (the direction that you counted).
Fill empty spaces with zeroes.
2.5 km = 2,500 m
Use the example above to fill in the blanks below. Figure out a pattern for each group of
conversions.
1 m = ___ cm
1 km = ____ m
1 dm = ___ cm
2 m = ___ cm
2 km = ____ m
__ dm = 20 cm
3 m = ___ cm
3 km = ____ m
3 dm = ___ cm
__ m = 400 cm
4 km = ____ m
4 dm = ___ cm
5 m = ___ cm
__ km = 5000 m
__ dm = 50 cm
