Unit Weight of concrete in kg/m3, kg/ft3, kN/m3, lbs/ft3 and lbs/in3.
Typical concrete is mixture of Portland stone cement fine aggregate (sand) and coarse aggregate with water. If it is used without provided with reinforcement/steel, then it is known as plain cement concrete and if it is used with reinforcement embeded, then it is known as reinforced cement concrete.

Genarally, Unit Weight of concrete is range from 2400 to 2500kg/m3 measured in Kilogram per cubic metre, and when it is measured in pound per cubic foot then it is range from 150 to 156lb/ft3.
What is the unit weight of concrete?Genarally, Unit Weight of concrete is range from 2400 to 2500kg/m3 measured in Kilogram per cubic metre, and when it is measured in pound per cubic foot then it is range from 150 to 156lb/ft3.
Weight of concrete depends on density of material cement, sand ,aggregate are used, water proportion, availability of void percentage in the mix, type of mix proportion and their compaction and shrinkage. Denser the concrete, higher its weight.
Unit weight of concrete is defined as ratio of weight of concrete to its unit volume, weight of concrete measured in kilogram (kg) and its volume is measured in cubic metre (m3), then its unit weight = unit mass/unit volume, represented as W = m/V, where W is concrete unit weights, m for mass and V for volume, it is also known as specific weight of concrete or density of concrete and their SI unit is kilogram per cubic metre (kg/m3).
Concrete unit weight generally depends on the entrapped air and water cement ratio but for estimation of different quantities and for making budget estimation before construction, we take unit weight of PCC (plain concrete cement) as 24KN per cubic meter and for RCC (reinforced cement concrete) as 25KN per cubic metre.
Unit Weight of concrete in kg/m3, kg/ft3, kN/m3, lbs/ft3 and lbs/in3
Typical concrete weight measured in different units like kilogram per metre, which is represented as kg/m3, kilogram per cubic foot ,indicated as kg/ft3, kilonewton per cubic meter, indicated as kN/m3, Pounds per cubic foot, indicates as lbs/ft3, Pounds per cubic inch, indicates as lbs/in3, kilogram per cubic centimetre, indicates as kg/cm3, etc.
Unit Weight of concrete as per IS 456
As per Indian standard, IS code 456, typical concrete unit weight measured in kg/m3, so their unit weight for PCC (plain concrete cement) is around 2400 kg per cubic meter and for RCC (reinforced cement concrete) is kept around 2500 kg per cubic metre.
Unit Weight of concrete in kN/m3
Typical concrete Unit Weight measured in kilo Newton per cubic metre, which is indicated as kN/m3, so their unit weight in kN/m3 for PCC (plain concrete cement) is around 24kN per cubic meter and for RCC (reinforced cement concrete) is kept around 25kN per cubic metre.
Unit Weight of concrete in kg/ft3
Typical concrete Unit Weight measured in kilogram per cubic foot, which is indicated as kg/ft3, so their unit weight in kg/ft3 for PCC (plain concrete cement) is around 68kg per cubic foot and for RCC (reinforced cement concrete) is kept around 71kg per cubic foot.
Unit Weight of concrete in kg/cm3
Typical concrete Unit Weight measured in kilogram per cubic centimeter, which is indicated as kg/cm3, so their unit weight in kg/cm3 for PCC (plain concrete cement) is around 0.0024kg per cubic centimeter and for RCC (reinforced cement concrete) is kept around 0.0025kg per cubic centimeter.
Unit Weight of concrete in lb/ft3
Typical concrete Unit Weight measured in pounds per cubic foot, which is indicated as lb/ft3, so their unit weight in lb/ft3 for PCC (plain concrete cement) is around 150 pounds per cubic foot and for RCC (reinforced cement concrete) is kept around 156 pounds per cubic foot.
Unit Weight of concrete in lb/in3
Typical concrete Unit Weight measured in pounds per cubic inch, which is indicated as lb/in3, so their unit weight in lb/in3 for PCC (plain concrete cement) is around 0.0867 pounds per cubic inch and for RCC (reinforced cement concrete) is kept around 0.0903 pounds per cubic inch.
