Basic Conversions & Decimal Fractions a Site Engineer should know so he/she can easily do estimation and inspection on site without any mistake.

Unit conversion for Civil Engineer plays an important role for quantity take-off of any material .

Conversion :

Following are some unit conversion for engineers:

1. 1cm =10mm

2. 1m = 100cm

3. 1km = 1000m

4. 1m = 3.28ft

5. 1foot = 12inch

6. 1tonne = 1000kg

7. 1m^2 = 10.76sq.ft

8. 1m^3 = 35.28cu.ft

9. 1gunta = 33'x33' = 1089sq.ft

10. 1acre = 40gunta

11. 1cu.ft = 28.135 litres

12. 1kg = 0.7litres

Decimal Fractions :

As we know that 1'= 12''. But we should aslo have to know that what fraction is for 1'' for the easy and speedy calculation.

We know, 1' = 12"

So,

1" = (1/12) = 0.08'

2" = (2/12) = 0.16'

3" = (3/12) = 0.25'

4" = (4/12) = 0.33'

5" = (5/12) = 0.41'

6" = (6/12) = 0.5'

7" = (7/12) = 0.58'

8" = (8/12) = 0.66'

9" = (9/12) = 0.75'

10" = (10/12) = 0.83'

11" = (11/12) = 0.91'

12" = (12/12) = 1'

So, as per above fractions 1'3'' = 1.25'

By using fractions the calculation become speedy and easy.
