Civil Engineering Measurements & Conversion Factors

Measurement is one of the most important things in civil engineering and without measurements, we can not complete any construction. Here I have listed some basic measurements and conversion factors which are most commonly used in civil engineering. Hope it will help you in your work.

Basic Quantities And Units:

Quantity	Dimension	SI Unit	FPS Unit
Mass	M	Kg	Slug
Length	L	M	Ft.
Time	T	Sec.	Sec.
Force	F	Newton (N)	Pound(lb)

Basic Standards:

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).

---

Metric Unit Of Weight/Mass:

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

---

Measurements Of Length:

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).

---

Metric Units For Liquid Measurements:

1 liter = 1000ml.

1 liter = 1kg.

1 kiloliter (1000 liters) = 1 cubic meter/ 1 cu.m/ 1 m3.

---

Conversion Factors:

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.

---

Measurements Of Area:

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

---

Miscellenius Conversion Factors:

1 cu.m = 35.32 cu.ft.

1 Pound = 4.448 Newton (Force).

1 klb = 4.448 kN.

1 Psi (lb/sq.in) = 6.689 Pascal (N/sq.m)

1 (lb/sq. ft) = 0.048 (kN/sq.m)
