Weight of steel bars per meter
For 6 mm dia bar, the weight will be 0.222 kg
For 8 mm dia bar, the weight will be 0.395 kg
For 10 mm dia bar, the weight will be 0.616 kg
For 12 mm dia bar, the weight will be 0.888 kg
For 16 mm dia bar, the weight will be 1.578 kg
For 20 mm dia bar, the weight will be 2.466 kg
For 25 mm dia bar, the weight will be 3.853 kg
For 32 mm dia bar, the weight will be 6.313 kg
For 40 mm dia bar, the weight will be 9.865 kg
Given below, the details of standard conversion factors:
1 inch = 25.4 mm
1 foot = 0.3048 m
1 yard = 0.9144 m
1 meter = 3.28 ft
1 mm = 0.0394 inch
1 mile = 1.6093 km
1 newton = 0.10 kg
the unit weight of various types of engineering materials.
Bitumen = 1340 kg/m3
Cement = 1440 kg/m3
Cast Iron = 7650 kg/m3
Steel = 7850 kg/m3
Ice = 913 kg/m3
Petrol = 690 kg/m3
Concrete grades are represented as M5, M10, M30 as per their compressive strength.
The “M” stands for Mix design of concrete succeeded by the compressive strength number in N/mm2
If we refer to M10 concrete, it signifies that the concrete contains 10 N/mm2 characteristic compressive strength at 28 days.
For M5 grade of concrete, mix proportion is 1:4:8
For M10 grade of concrete, mix proportion is 1:3:6
For M15 grade of concrete, mix proportion is 1:2:4
For M20 grade of concrete, mix proportion is 1:1.5:3
For M25 grade of concrete, mix proportion is 1:1:2
The following formula is applied to know the weight of the steel bars
W = (D ^ 2 x L) / 162
D: denotes the diameter of the bars
L: indicates the total length of the steel bars for which the weight is to be measured.
For example, if it is necessary to calculate the weight of 20 mm steel bars, the calculation will be as follows: -W = 20 ^ 2/162 = 2,466 kg / meter
A conversion factor is a number used to transform one set of units into another by multiplying or dividing it. When converting, the exact conversion factor to an identical value must be applied. For example, to convert inches to feet, the exact conversion value should be 12 inches, which equals 1 foot.
