How to use the unit converter

Choose a category such as Length, Weight or Area.
Enter the value and select the "From" and "To" units. Use the ⇄ button to swap them.
The result and the conversion formula appear instantly, along with the value in every other unit of that category.

Formulas

Length	`1 inch = 2.54 cm · 1 foot = 30.48 cm · 1 mile = 1.609344 km`
Weight	`1 kg = 2.20462 lb · 1 tola = 11.6638 g · 1 quintal = 100 kg`
Temperature	`°F = °C × 9/5 + 32 · K = °C + 273.15`
Area	`1 acre = 43,560 sq ft = 100 cents · 1 gaj = 9 sq ft · 1 hectare ≈ 2.471 acres`
Speed	`km/h × 5/18 = m/s · m/s × 18/5 = km/h`

Solved examples

Example 1: Convert 72 km/h into m/s.

72 × 5/18

Answer: 20 m/s

Example 2: A plot is 200 gaj. What is its area in square feet?

1 gaj (square yard) = 9 sq ft
200 × 9

Answer: 1,800 sq ft

Example 3: Convert 37 °C to Fahrenheit.

37 × 9/5 + 32 = 66.6 + 32

Answer: 98.6 °F

Indian land measurement units

Land in India is still commonly measured in local units. A gaj is a square yard (9 sq ft), widely used in North India for plots. A cent (435.6 sq ft, or 1/100 of an acre) is common in Kerala and Tamil Nadu, and a guntha (1,089 sq ft, or 1/40 of an acre) is used in Maharashtra, Karnataka, Telangana and Gujarat.

Bigha, biswa and kanal vary from state to state, so they are not included here — always confirm their local value before a property transaction.

Speed conversion shortcut for exams

Time-speed-distance questions often mix km/h and m/s. Multiply km/h by 5/18 to get m/s, and multiply m/s by 18/5 to get km/h. For example, 90 km/h = 25 m/s.

Frequently asked questions

How many square feet are in an acre?

One acre is exactly 43,560 square feet, which is about 4,046.86 square metres.

How do I convert Celsius to Fahrenheit?

Multiply by 9/5 and add 32. For example, 25 °C × 9/5 + 32 = 77 °F.

How many square feet is 1 gaj?

One gaj is one square yard, which is 9 square feet or about 0.836 square metres.

Is 1 GB equal to 1000 MB or 1024 MB?

In computing, 1 GB is traditionally 1,024 MB (binary units), which this converter uses. Storage manufacturers often use 1 GB = 1,000 MB, which is why a drive may show less space than advertised.
