Calculators

Area / Volume / General Calculation
  • There are 1000 litres in one cubic metre
  • 1 cubic metre of product covers 10 square metres to a depth of 100mm
  • 20 x 50 litre bags of product make 1 cubic metre
  • A roll of turf covers 1 square metre. (0.5m wide x 2m long)
  • 1m3 Mulches / Soils / Lawn Builder covers 25m2 @ 40mm OR 50m2 @ 20mm
  • 1 ton Sand / Aggregate / Pebbles covers Approx. 14m2 @ 50mm
  • Concrete Mix - 0.5m3 = Approx. 1t
  • Concrete Mix - Approx. 9 Builders Barrows = 1m3

Working out m2

Length x Width = M2
e.g. 6m x 5m = 30m2

Working out m3

Length x Width x Depth = M3
e.g. 6m x 5m x 2m = 60m3
