What is a Unit Converter?

A Unit Converter changes a measurement from one unit into another equivalent unit while preserving the same physical quantity.

For example:

1 meter = 100 centimeters

1 kilometer = 1,000 meters

1 kilogram = 1,000 grams

1 kilogram ≈ 2.20462 pounds

A conversion does not change the actual quantity; it only changes the way that quantity is expressed.

How to Use DigiSadhan Unit Converter?

Using the online calculator is simple:

Step 1: Enter a Value

The page provides a simple From → To → Convert interface.

Unit Conversion Formula

The general conversion formula is:

Converted Value = Original Value × Conversion Factor

For example, to convert meters into centimeters:

Centimeters = Meters × 100

Therefore:

5 × 100 = 500 cm

So:

5 meters = 500 centimeters

For reverse conversion:

Meters = Centimeters ÷ 100

Length Conversion Formulas

Centimeter to Meter

Meter = Centimeter ÷ 100

Example:

250 cm ÷ 100

= 2.5 meters

Therefore:

250 cm = 2.5 m

Meter to Centimeter

Centimeter = Meter × 100

Example:

4 m × 100

= 400 cm

Kilometer to Meter

Meter = Kilometer × 1,000

Example:

3 km × 1,000

= 3,000 m

Meter to Kilometer

Kilometer = Meter ÷ 1,000

Example:

5,000 m ÷ 1,000

= 5 km

The metric relationships are based on decimal SI prefixes.

Weight and Mass Conversion Formulas

Gram to Kilogram

Kilogram = Gram ÷ 1,000

Example:

2,500 g ÷ 1,000

= 2.5 kg

Kilogram to Gram

Gram = Kilogram × 1,000

Example:

7 kg × 1,000

= 7,000 g

Kilogram to Pound

Using the international conversion:

Pounds = Kilograms × 2.20462

Example:

10 kg × 2.20462

= 22.0462 lb

Therefore:

10 kg ≈ 22.05 pounds

NIST’s conversion tables give approximately 1 kilogram = 2.20 pounds for practical conversion.

Pound to Kilogram

Kilograms = Pounds × 0.45359237

Example:

10 lb × 0.45359237

= 4.5359237 kg

Therefore:

10 lb ≈ 4.54 kg

Celsius Temperature Conversion

Temperature conversion is different from simple multiplication because Celsius and Fahrenheit have different zero points.

Celsius to Fahrenheit

°F = (°C × 9/5) + 32

Example

25°C:

(25 × 9/5) + 32

= 45 + 32

= 77°F

Therefore:

25°C = 77°F

Fahrenheit to Celsius

°C = (°F − 32) × 5/9

Example

98.6°F:

(98.6 − 32) × 5/9

= 37°C

NIST provides these temperature conversion relationships as standard conversions.

Celsius to Kelvin Formula

For scientific calculations, Celsius can also be converted to Kelvin:

K = °C + 273.15

Example:

25°C + 273.15

= 298.15 K

Reverse:

°C = K − 273.15

Therefore:

298.15 K − 273.15

= 25°C

Common Unit Conversion Table
