UNIT 1


Conversions


Sara received the keys to her new low-cost house. In order to finish the house, which came with only the most basic fixtures, Sara had to do a lot of measuring and converting of measurements.


Converting in the metric system


We measure using units of measurement in the metric system (Système International). Converting between units in the metric system is easy to understand because the units are based on the decimal system.


× 1 000 km ÷ 1 000 Figure 1 Converting units of length


• To convert to a larger unit, divide by the conversion factor. • To convert to smaller unit, multiply by the conversion factor.


Worked example 1


Sara wants a ceiling in her house. Her son measures the lengths of some of the walls as follows: 3 752 mm; 354,5 cm; 4,1 m.


Use the information in the Remember box to convert all the measurements to: 1 millimetres 2


centimetres 3 metres.


Answers 1


Millimetres: 3 752 mm; 3 545 mm; 4 100 mm


2 Centimetres: 375,2 cm; 354,5 cm; 410,0 cm 3 Metres: 3,752 m; 3,545 m; 4,1 m


Remember


To convert: • metres to centimetres, multiply by 100 (1 m = 100 cm)


• centimetres to metres, divide by 100 (1 cm = 1


___ 100 m).


m ÷ 100 × 100 cm


÷ 10 ×10
