CONVERSION OF UNITS

Height Conversion

Subject 1– 144cm

If 1cm=0.393700787 inches

Therefore, 144cm:

144*0.393700787

=56.692913328 Inches

=56.69 Inches

Subject 2- 168cm

If 1cm=0.393700787 inches

168cm:

168*0.393700787

=66.141732216Inches

=66.14Inches

Subject 3178cm

If 1cm=0.393700787 inches

178cm:

178*0.393700787

=70.078740086Inches

=70.08Inches

Subject 4162cm

If 1cm=0.393700787 inches

162cm:

162*0.393700787

=63.779527494

= 63.78 Inches

Weight Conversion

1 Kilogram=2.20462262pounds

Subject 1

If 1kg=2.20462262pounds

45kg:

45*2.20462262

=99.2080179Pounds

=99.21Pounds

Subject 2

If 1kg=2.20462262Pounds

61kg:

61*2.20462262

=134.48197982Pounds

=134.48Pounds

Subject 3

If 1kg=2.20462262Pounds

72kg:

72*2.20462262

=158.73282864Pounds

=158.73Pounds

Subject 4

If 1kg=2.20462262Pounds

64kg:

64*2.20462262

=141.09584768Pounds

=141.10Pounds

It is important to follow a standard system of measurement because of many reasons. Firstly, it makes a given unit of measurement standard in all parts of the world. Therefore 1000Kilomeres will the same whether one is in Britain, Germany, Holland or Kenya. Next, all conversions are made universal. Therefore conversion from one unit to another only requires multiplication or division by a given factor. Also it makes figures easy to use and comprehend, because one is then able to compare prices or weights no matter the part of the world they are in. (Soman, 2009)

A scenario where standardization is important could be when one falls ill. Then say they have to be flown from their country to another country, say India, The weight and height taken in their country should be able to be compared to that in the foreign country so as to assess all aspects of their health conclusively. If there wasn’t an international standard of units or a conversion formula, the two different weights and heights cannot be compared accurately. (Taylor,1995)
