In your day-to-day life, you might need to convert from one unit to another. To Perform the Required Calculations you might need to learn about Mathematical Conversions. Thus, it is necessary to learn about Unit Conversions to change from one unit to another unit. Before understanding the Units of Measurement you need to be aware of the relationship between them.
Go through the entire article to learn about units of length conversion chart, unit of mass and weight conversion chart, unit of time conversion chart, units of capacity and volume conversion chart, unit of a temperature conversion chart, etc. Math Conversion Charts are quite important and interesting to learn.
What is Conversion of Units?
Depending on the Situation each unit differs. For instance, the area of the room is expressed in Meters whereas the thickness of the pencil is expressed in mm. Thus, it is necessary to convert from one unit to another.
Importance of Mathematical Conversions
In Order to have accuracy and avoid confusion in measurement, we need to change from one unit to another. For example, we will measure the length of the pencil in cm but no in km. Likewise, we need to convert from one unit to another. While converting from one unit to another of the same quantity we use multiplicative conversion factors. Let’s see how to convert different units of length and mass in the later modules.

Length Conversion Table
| 1 km = 10 hm
1 hm = 10 dam 1 dam = 10 m 1 m = 10 dm 1 dm = 10 cm 1 cm = 10 mm 1mm = \(\frac { 1 }{ 10 } \) cm 1 cm = \(\frac { 1 }{ 10 } \) dm 1 dm = \(\frac { 1 }{ 10 } \) m 1m = \(\frac { 1 }{ 10 } \) dam 1 dam = \(\frac { 1 }{ 10 } \) hm 1hm = \(\frac { 1 }{ 10 } \) km |
Mass Conversion Table
| 1 kg = 10 hg
1 hg = 10 dag 1 dag = 10 g 1 g = 10 dg 1 dg = 10 cg 1 cg = 10 mg 1 mg = \(\frac { 1 }{ 10 } \) cg 1 cg = \(\frac { 1 }{ 10 } \) dg 1 dg = \(\frac { 1 }{ 10 } \) g 1 g = \(\frac { 1 }{ 10 } \) dag 1 dag = \(\frac { 1 }{ 10 } \) hg 1 hg = \(\frac { 1 }{ 10 } \) kg |
Capacity Conversion Table
| 1 kℓ = 10 hℓ
1 hℓ = 10 daℓ 1 daℓ = 10 ℓ 1 ℓ = 10 dℓ 1 dℓ = 10 cℓ 1 cℓ = 10 mℓ 1 mℓ =\(\frac { 1 }{ 10 } \) cℓ 1 cℓ = \(\frac { 1 }{ 10 } \) dℓ 1dℓ = \(\frac { 1 }{ 10 } \) ℓ 1 ℓ = \(\frac { 1 }{ 10 } \) dℓ 1 daℓ = \(\frac { 1 }{ 10 } \) hℓ 1 hℓ = \(\frac { 1 }{ 10 } \) kℓ |
Points to remember:
- To convert bigger units to smaller units multiply
- To convert smaller units to bigger units divide
Solved Examples on Conversion of Units
1. Convert 4 cm to km?
Solution:
Step 1:
Draw a line or box as below
| km | hm | dam | m | dm | cm | mm |
Step 2:
Put 1 at the larger unit to be converted.
Here we want to convert cm to km,
Since km is the larger unit, thus put 1 under the corresponding column (km).
| km
1 |
hm
|
dam
|
m
|
dm
|
cm
|
mm
|
Step 3:
Now place 0 till the smaller unit
| km
1 |
hm
0 |
dam
0 |
m
0 |
dm
0 |
cm
0 |
mm
|
Since the conversion is from a smaller unit to larger we need to divide the given length by 100000 i.e. 105
4 cm = 4/105
= 0.00004 km
2. Convert 7 gms to milligrams?
Solution:
We need to convert grams to milligrams
We know 1 gram = 1000 mg
Thus 7 g = 7*1000
= 7000 mg
