Metre The metre is the base unit of the length of SI. All the other units have a prefix and the word metre. When you change units you must either divide or multiply by powers of 10. dm = decimetre dam = decametre hm = hectometre

km hm dam m dm cm mm **Trick: Kids Hate Damn Muffins Damn Crappy Muffins km ↔ hm ↔ dam ↔ m ↔ dm ↔ cm ↔ mm → = ÷ 10 ← = x 10

4
Metres and Grams Metres, litres and grams are similar. Metres measures length Grams measures mass Litres measures liquids

5
Examples km hm dam m dm cm mm 4m = km 400km = m 40cm =m 40cm =km

6
More examples: How many millimetres in: 1) 7.5cm = 2) 0.0054km = 3) 0.1dm =

7
Last examples: 2kg + 4hg + 100mg + 87dam = 2l + 35dl + 57cl + 0.3hl =
