Different works are carried out in the civil engineering sectors. All different works have different units; some works’ units may be the same. Some of the units in civil engineering are:

34 | Supply of cement | Bag | Per bag |
35 | Supply of steel, G.I. sheet, bare electric line | Quintal | Per quintal |
36 | Supply of GI sheet | m² | m² |
37 | Supply of sanitary items | Number | Per number |
38 | Supply of paint, varnishes | Litre | Per litre |
39 | Supply of explosives, stiff paint | Kg | Per kg |
2. Basic Standards
The basic standards units are as follows:
1 inch = 25.4 millimeters = 2.54cm.
1 meter = 39.37 inches =1.09 yards.
1 liter = 0.22 galls (imp.)
1 gallon (imp.) = 4.546 liters.
1 gallon (US) = 3.785 liters.
1 Kilogram (kg) = 2.2046 pounds (lb).
3. Metric Unit of Weight/Mass
The metric unit of weight/mass is as follows:
1 tonne = 1000 kilograms = 1,000,000 grams.
1 quintal = 100 kilograms = 100,000 grams.
1 Slug = 14.606 kg
1 Slug = 32.2 lb
4. Measurement of Length
These are the majorly used units in civil engineering. The measurement of length is done in the following ways:
1 foot = 12 inches.
1 yard = 3 feet.
1 furlong = 220 yards.
1 mile = 8 fulongs.
1 Kilometer (Km) = 1000 meters.
1 meter (m) = 100 centimeters (cm).
1 cm = 10 millimeter (mm).
5. Metric Units For Liquid Measurements
The metric units for liquid measurements are as follows:
1 liter = 1000ml.
1 liter = 1kg.
1 kiloliter (1000 liters) = 1 cubic meter/ 1 cu.m/ 1 m³.
6. Conversion Factors
The conversion factors are as follows:
1 cu. ft. = 28.317 liters.
1 cu. ft. = 0.028 cu. meters.
1 cu. ft. = 6.24 galls (imperial).
1 cu. ft. = 7.48 galls (US).
1 imp. gall = 1.20 galls (US), liquid.
1 imp. gall = 1.03 galls (US), dry.
7. Measurement of Area
The measurement of the area is as follows:
1 Acre = 43560 sq. ft
1 Acre = 4046.46 sq. m
1 Acre = 8 Kanals.
1 Kanal = 20 Marlas.
1 Marla = 225 sq. ft (* in some regions 272 sq. ft)
1 Marla = 15.50 sq.m
Hope you got the idea of units in civil engineering.
