BASIC LAND UNIT CONVERSION

1) 1m = 1000 mm = 100 cm

2) 1 inch = 25.4 mm = 25 mm  (Approx)

3) 1 Ft = 12 inch = 304.8 mm = 0.3048 mm = 300 mm (Approx)

4) 1 Guntha = 33 ft x 33 ft = 1089 sq.ft = 1000 sq.ft (Approx)
   
    In Meter = 0.3048 x 0.3048 = 10.01 x 10.01 = 101.16 m^2 = 100 m^2 (Approx)

5) 1 Acre = 40 Guntha = 1089 x 40 = 43560 sq.ft

     In Meter = 101.16 x 40 = 4046.4 m^2 = 4000 m^2 (Approx)

6) 1 Hectare = 2.5 Acre = 10116 m^2 = 10000 m^2 (Approx)

7) 1 Brass = 

    Area = 10 ft x 10 ft = 100 sq.ft

    Volume = 10 ft x 10 ft x 1 ft = 100 ft^3

8) 1 Yard = 0.914 m

9) 1 Mile = 1.62 km

10) 1 Gallon = 3.785 litres and 1 Barrel = 42 gallon = 159 litres

11) 1 m^3 = 1000 Litres 

UNIT CONVERTER

* CONVERSION OF 'FT' TO 'M'

Let take some examples -

1) 7'8" = in mm 300 25 = 2100 + 200 = 2300 mm = 2.3 M

2) 6'14" = 7'2" = in mm 300 25 = 2100 + 50 = 2150 mm = 2.15 M

* CONVERSION OF 'MM' TO 'FT'

Let take some example -

1) 4000 mm = 4000 / 300 = 13 remain 100 = 100 / 25 = 4

Therefore 4000 mm = 13'4"

Hope this information will be useful to you all.
