To convert centimetres to metres, divide by 100. 1000 ÷ 100 = 10 m. For length conversion, use the relation between the two units and multiply when changing from a larger unit to a smaller unit. Because centimetre is the smaller unit, there are 100 centimetres in 1 metre; moving from cm to m means grouping centimetres into hundreds. Check the decimal place carefully and keep the final answer in metres, not centimetres.
