Meas2.docx CONVERTING UNITS Work through the Meas2a powerpoint. METRIC CONVERSIONS Complete the conversion rates for length, mass and capacity by filling in the gaps. LENGTH MASS CAPACITY 1cm = ………mm 1g = ……………mg 1cl = ………ml 1m = ………..mm or ………cm 1kg = …………g 1l = …………ml 1km = …………m 1T = ……………kg BSM: To convert from bigger sized units to smaller sized units, MULTIPLY by the conversion rate. SBD: To convert from smaller sized units to bigger sized units, DIVIDE by the conversion rate. Examples Work out the answers to the examples given in the powerpoint, showing all your workings. Convert 7 metres into millimetres. Ans: 7m = ………………mm ………………………………………………………………………………………………………………………………………… ………………………………………………………………………………………………………………………………………… Convert 85 millilitres into centilitres. Ans: 85ml = ………………cl ………………………………………………………………………………………………………………………………………… ………………………………………………………………………………………………………………………………………… Convert 0.64 kilometres into millimetres Ans: 0.64km = …………………mm ………………………………………………………………………………………………………………………………………… ………………………………………………………………………………………………………………………………………… -6- Meas2.docx Work through the MyMaths lesson and its online homework called Metric Conversion found at: http://app.mymaths.co.uk/279-resource/metric-conversion http://app.mymaths.co.uk/279-homework/metric-conversion Work through the Meas2b powerpoint. METRIC-IMPERIAL CONVERSIONS Fill-in the approximate equivalents given in the powerpoint. Length: 30cm (ruler) ≈ …………… inches (or ……… foot) 1 yard = 3 feet ≈ 3 x 30cm ≈ ……………cm 8 kilometres ≈ ……………miles Mass: 1 ounce ≈ ……………g 1 kilogram (bag of sugar) ≈ …………… pounds Capacity: 1 litre (carton of milk) ≈ ……………pints 1 gallon (of petrol) ≈ ……………litres To convert from one type of unit to another DIVIDE by the conversion value of the ‘common unit’ (the type you have been told) and then MULTIPLY by the conversion value of the unit you want to change into.
