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 conversions of units help in accurate measurement comparison.

How to Convert Unit of Measurement?

To convert units of measurement efficiently, follow these steps:

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

Understanding conversion of measurement ensures accurate calculations across different measurement systems.

Conversion of Units of Weight

1 kilogram (kg) = 1000 grams (g).

To convert from kg to g: Multiply by 1000.
Example: 5 kg = 5 * 1000 = 5000 g

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

Table of Unit conversion for Weight

The table for conversion of weight is:

From	To	Conversion Factor
1 kilogram (kg)	grams (g)	1 kg = 1000 g
1 gram (g)	milligrams (mg)	1 g = 1000 mg
1 milligram (mg)	grams (g)	1 mg = 0.001 g
1 quintal	kilograms (kg)	1 quintal = 100 kg
1 metric tonne (t)	kilograms (kg)	1 t = 1000 kg
1 pound (lb)	grams (g)	1 lb = 453.592 g
1 ounce (oz)	grams (g)	1 oz = 28.35 g
1 stone	kilograms (kg)	1 stone = 6.35 kg
1 ton (US)	kilograms (kg)	1 US ton = 907.184 kg
1 ton (UK)	kilograms (kg)	1 UK ton = 1016 kg

Conversion of Units of Capacity

To convert litres (L) to millilitres (mL): Multiply by 1000.
Example: 2 L = 2 * 1000 = 2000 mL

To convert millilitres (mL) to litres (L): Divide by 1000.
Example: 2000 mL = 2000/1000 = 2 L

Table of Unit conversion for Capacity

The table for conversion of capacity is:

From	To	Conversion Factor
1 liter (L)	milliliters (mL)	1 L = 1000 mL
1 milliliter (mL)	liters (L)	1 mL = 0.001 L
1 kiloliter (kL)	liters (L)	1 kL = 1000 L
1 gallon (US)	liters (L)	1 gallon = 3.785 L
1 gallon (UK)	liters (L)	1 gallon = 4.546 L
1 pint (US)	milliliters (mL)	1 pint = 473.176 mL
1 pint (UK)	milliliters (mL)	1 pint = 568.261 mL
1 fluid ounce (US)	milliliters (mL)	1 fl oz = 29.5735 mL
1 fluid ounce (UK)	milliliters (mL)	1 fl oz = 28.4131 mL
1 cup	milliliters (mL)	1 cup = 240 mL

Conversion of Units of Length

1 kilometre (km) = 1000 metres (m).

To convert km to m: Multiply by 1000.
Example: 7 km = 7 * 1000 = 7000 m

To convert m to km: Divide by 1000.
Example: 7000 m = 7000/1000 = 7 km

Table of Unit Conversion for Length

The table for conversion of length is:

From	To	Conversion Factor
1 kilometre (km)	metres (m)	1 km = 1000 m
1 metre (m)	centimetres (cm)	1 m = 100 cm
1 centimetre (cm)	millimetres (mm)	1 cm = 10 mm
1 millimetre (mm)	centimetres (cm)	1 mm = 0.1 cm
1 metre (m)	millimetres (mm)	1 m = 1000 mm
1 kilometre (km)	centimetres (cm)	1 km = 100,000 cm
1 inch (in)	centimetres (cm)	1 in = 2.54 cm
1 foot (ft)	inches (in)	1 ft = 12 in
1 foot (ft)	centimetres (cm)	1 ft = 30.48 cm
1 yard (yd)	metres (m)	1 yd = 0.9144 m
1 mile (mi)	kilometres (km)	1 mi = 1.609 km

Conversion of Units of Time

1 hour (h) = 60 minutes (m).

To convert hours to minutes: Multiply by 60.
Example: 3 hours = 3 * 60 = 180 minutes

To convert minutes to seconds: Multiply by 60.
Example: 180 minutes = 180 * 60 = 10,800 seconds

To convert minutes to hours: Divide by 60.
Example: 180 minutes / 60 = 3 hours

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

Day to hours: 1 day = 24 hours.
Example: 3 days = 3 * 24 = 72 hours

Week to days: 1 week = 7 days.
Example: 2 weeks = 2 * 7 = 14 days

Year to days: 1 year = 365 days (or 366 in a leap year).
Example: 2 years = 2 * 365 = 730 days

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

The symbols (>), (<) and (=) help compare measurements:

1. Greater than (>): A = 51 cm, B = 49 cm ? A > B

2. Less than (<): X = 12 cm, Y = 13 cm ? X < Y

3. Equal to (=): P = 45 cm, Q = 45 cm ? P = Q

Understanding units conversion and conversion units is crucial for accurate measurement comparison.
