What is the Unit of Conversion?

The "unit of conversion" refers to the specific unit or measurement that you are using to convert from one unit to another in a conversion process. In other words, it's the unit of measurement that you are starting with and want to convert into a different unit, for example, converting kilometres to metres, milligrams to kilograms or days to hours. These units of conversion make it easier to compare and understand quantities expressed in different units.

How to Convert Unit of Measurement?

To convert units of measurement, follow these steps:

1. Identify the starting unit and target unit.
2. Find the conversion factor relating the two units (e.g., 1 metre = 100 centimetres).
3. Use multiplication or division to apply the conversion factor to the quantity being converted.
4. Perform the calculation to obtain the converted value in the target unit.
5. Express the result with the appropriate unit and precision.

Remember that the numerical value may change, but the quantity remains the same, ensuring accurate communication and compatibility across different systems.

Conversion of Units of Weight

1 kilogram (kg) is equal to 1000 grams (g).

To convert from kg to g: Multiply the number of kilograms by 1000.
Example: 5 kg = 5 x 1000 = 5000 g

To convert from g to kg: Divide the number of grams by 1000.
Example: 5000 g = 5000/1000 = 5 kg

Conversion of Units of Capacity

To convert litres (L) to millilitres (mL): Multiply the number of litres by 1000.

Example: 2 litres = 2 x 1000 = 2000 millilitres

To convert millilitres (mL) to litres (L): Divide the number of millilitres by 1000.

Example: 2000 millilitres = 2000 / 1000 = 2 liters

Conversion of Units of Length

1 kilometre (km) is equal to 1000 metres (m).

To convert kilometres(km) to metres(m): Multiply the number of kilometres by 1000.

Example: 7 km = 7 x 1000 = 7000 metres

To convert metres (m) to kilometres(km): Divide the number of metres by 1000.

Example: 7000 metres = 7000 / 1000 = 7 km

Conversion of Units of Time

1 hour(h) is equal to 60 minutes(m).

To convert hours to minutes: Multiply the number of hours by 60.

For example, 3 hours = 3 x 60 = 180 minutes

To convert minutes to seconds: Multiply the number of minutes by 60:

For example, 180 minutes = 180 x 60 = 10,800 seconds

To convert minutes to hours: Divide the number of minutes by 60:

For example, 180 minutes ÷ 60 = 3 hours

To convert seconds to minutes: Divide the number of seconds by 60:

For example, 10,800 seconds ÷ 60 = 180 minutes

Conversion of Day to Hours, Week to Days, Year to Days

Day to hours:

Conversion factor: 24 hours/day

Example: 3 days = 3 x 24 hours = 72 hours

Week to days:

Conversion factor: 7 days/week

Example: 2 weeks = 2 x 7 days = 14 days

Year to days:

Conversion factor: 365 days/year (or 366 days in a leap year)

Example 1: 1 year = 365 days = 365 x 1 = 365 days

Example 2: 2 years = 2 x 365 days = 730 days

Use of >, < and = in Problems Based on Comparison of Measurements

The symbols '>', '<' and '=' are used in problems based on comparison of measurements to represent the relative size of two or more quantities.

1. Greater than: The symbol '>' is used to indicate that one quantity is greater in value than another. For example:

A = 51 cm
B = 49 cm
A > B

2. Less than: The symbol '<' is used to indicate that one quantity is smaller in value than another. For example:

X = 12 cm
Y = 13 cm
X < Y

3. Equal to: The symbol '=' is used to indicate that two or more quantities have the same value. For example:

P = 45 cm
Q = 45 cm
P = Q

Note: It is important to keep in mind that these symbols are used to compare only the values of the quantities not the units of measurement.
