Calculations & Conversions

Standard Conversion:

  • 3 Feet = 1 Yard
  • 9 Square Feet = 1 Square Yard
  • 27 Cubic Feet = 1 Cubic Yard
  • 5,280 Feet = 1 Mile
  • 43,560 Square Feet = 1 Acre
  • 2000 Pounds = 1 Ton

Area Conversions:

  • Length [FT] x Width [FT] = Area [SQFT]
  • Area [SQFT] / 9 = Area [SY]

Volume Conversions:

  • Length [FT] x Width [FT] x Depth [FT] = Volume [CUFT]
  • Volume [CUFT] / 27 = Volume [CY]

Standard Weights:

  • Sand = 2,700 LBS per Cubic Yard
  • Concrete = 150 LBS per Cubic Foot
  • Limerock/Granite GAB = 105 LBS per Inch per Square Yard
  • Asphalt = 110 LBS per Inch per SY
    • 1 Inch of Asphalt = 110 LBS / SY
    • 1.5 Inches of Asphalt = 165 LBS / SY
    • 2.0 Inches of Asphalt = 220 LBS / SY

Examples:

Sand – How many tons of sand are needed to fill in a 50 FT x 50 FT area 1 FT Thick?<

  • 50 FT x 50 FT x 1 FT = 2,500 CF / 27 = 92.5 CY x 2,700 LBS/CY = 249,750 LBS / 2000 LBS/TON = 125 Tons

Concrete – How Many Cubic Yards of Concrete are needed to fill in a 10 FT x 10 FT area 6 Inches Thick?

  • 10 FT x 10 FT x 0.5 FT = 50 CF / 27 = 1.8 Cubic Yards

    Limerock/Granite GAB–How many tons of GAB is needed to construct a 10FT wide x 100FT long Driveway 6 Inches thick?

    • Area[SY] x Thickness[Inch] x 105 LBS / 2000 = Tons of GAB
    • 10 FT x 100 FT = 1,000 SQFT / 9 = 111 SY x 6 IN x 105 LBS / 2000 = 35 TONS

    Asphalt – How Many Tons of Asphalt is needed to pave 1 Mile of Road 24 FT wide with 2 Inches of Asphalt?

    • 1 Mile x 5,280 LF/Mile = 5,280 LF x 24 FT = 126,720 SF / 9 = 14,080 SY x 2 Inches x 110 LBS / 2000 = 1,548 Tons
