• Measure from the 0 mark, not from the end of the ruler. Most rulers have a small margin before the scale begins, and starting there is the commonest source of a wrong answer.
• Each numbered mark is 1 centimetre and each small mark between them is 1 millimetre, so 10 mm = 1 cm and 6 cm = 60 mm.
• To convert centimetres to millimetres, multiply by 10: 6 × 10 = 60 mm. To go the other way, divide by 10.
• To convert centimetres to metres, divide by 100: 6 ÷ 100 = 0.06 m.
• One inch is exactly 2.54 cm, so 6 cm ÷ 2.54 is about 2.36 in.
