CIVIL ENGINEERING MEASUREMENTS & CONVERSION FACTORS

Measurement is one of the 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:

 BASIC STANDARDS:

1 inch = 25.4 mm = 2.54 cm.
1 meter = 39.37 inches = 1.09 yards.
1 liter = 0.22 galls (imp.)
1 gallon (imp.) = 4.546liters. 
1 gallon (US) = 3.785 liters.
1 kilogram (kg) = 2.2046 pounds(lb).
--------------------------------------------------------------
METRIC UNIT OF WEIGHT / MASS :

1 tonne = 1000 kilograms = 10,00,000 grams.
1 quintal = 100 kilograms = 1,00,000 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 furlongs.
1 kilometer = 1000 meters.
1 cm = 10 mm.
-----------------------------------------------------------------
METRIC UNITS FOR LIQUID MEASUREMENTS:

1 liter = 100 ml.
1 liter = 1 kg.
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.m
1 cu.ft = 6.24 galls(imp.)
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
-----------------------------------------------------------------
MISCELLANEOUS 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).
