EXPLANATION FOR CONVERSION FROM SMALL UNIT TO BIG UNIT :-
▪ Write the short table from kilogram to centigram or gram to centigram.
▪ Fill up the given values.
▪ The remaining units are filled up with zeroes.
All the values together gives the answer
1. To convert a lower unit into a higher unit, Divide by 10 or 100 or 1000.
2. Division by 10, 100, 1000 is done by shifting the decimal point to the left of the given numbers.
There are some examples are given below for your better understanding -
Example.1) Convert 872 grams into kilograms. (When we convert smaller to bigger unit => division)
Ans.)
kg hg dag g
0 8 7 2 = 0.872 kg
Alternatively -
As we know that, 1 kg = 1000 gm
1
So, 1 gm = --------- kg
1000
872
Now, 872 gm = --------------- = 0.872 kg (Ans.)
1000
Example.2) 8mg to dg
Ans.) dg cg mg
0 0 8 = 0.08
Alternatively -
As we know that, 1 decigram = 100 mg
1
1 mg = --------- decigram = 0.01 decigram
100
8
So, 8 mg = -------- = 0.08 dg (Ans.)
100
