Volume Calculator
To work out the volume you require simply multiply Width x Length x Depth
Example
5m wide x 3m long x 0.05m(50mm) deep = 0.75m3 = one bag Approx
3m wide x 5m long x 0.1m(100mm) deep = 1.5m3 = two bags Approx
To work out the volume of a circle/pond you use
Half the Diameter to give us the radius then
Radius x Radius x 3.14 x depth = Volume
Example
Diameter is 3m and we need 225mm depth
so divide Diameter 3m by 2 = 1.5m Radius
Then simply multiply 1.5 x 1.5 radius x 3.14 x 0.225(225mm) deep = 1.59m3
= two bags Approx

Conversion Factors
Volume
cu/YARDS
1m3= 1.3 cubic yards
To convert cubic yards to cubic meters multiply by 0.7646
Example
You have 13 cubic yards so multiply 13 x 0.7646= 10 cubic meters (10m3)
cu/FEET
1m3= 35.3 cubic feet
To convert cubic feet to cubic meters multiply by 0.02832
Example
You have 353 cubic feet so multiply 353 x 0.02832= 10 cubic meters (10m3)
cu/FEET tocu/YARDS
1 cubic yard= 27 cubic feet
To convert cubic feet to cubic yards divide by 27
Example
You have 270 cubic feet so divide 270'/.27= 10 cu/yards (yd3)
Area
sq/FEET
1 square yard= 9 square feet
To convert square feet to square yards divide by 9
Example
You have 90 square feet so divide 90'/.9= 10 sq/yards (yd2)
m2 to yd2
1 square meter=1.19599 square yards
To convert square meters to square yards multiply by1.19599

INCHES
Straight Line Conversion Only (This is NOT a Volume or Area conversion)
Do not try to use Inches to work out Volume the numbers are too big !
1 Inch= 25.4mm
To convert Inches to millimeters multiply by 25.4
Example
You have 3 Inches so multiply 3 x 25.4= 76.2mm (0.0762m)
