Handy conversion facts

1 inch2.54 cm
1 foot30.48 cm
1 mile1.609 km
1 kg2.2046 lb
1 tola11.66 g
1 quintal100 kg
1 litre0.264 US gallon

All conversions use exact international definitions. For example, the inch is defined as exactly 2.54 cm and the pound as exactly 0.45359237 kg.

Example: height in feet and centimetres

A height of 5 feet 7 inches is 67 inches. 67 × 2.54 = 170.18 cm. Going the other way, 170 cm ÷ 2.54 = 66.9 inches ≈ 5 ft 7 in.

Example: temperature

A fever of 102 °F in Celsius: (102 − 32) × 5 ÷ 9 = 38.9 °C.

°C = (°F − 32) × 5 ÷ 9   ·   °F = °C × 9 ÷ 5 + 32

Data units: KB, MB, GB

Phone and computer storage can be confusing because there are two systems:

  • Decimal (used by storage makers): 1 kB = 1,000 bytes, 1 MB = 1,000 kB, 1 GB = 1,000 MB.
  • Binary (used by many operating systems): 1 KiB = 1,024 bytes, 1 MiB = 1,024 KiB, 1 GiB = 1,024 MiB.

Online forms that ask for a photo “under 50 KB” usually mean 50 × 1,024 bytes. To get a photo to an exact size, use the image compressor.

Indian units

  • Tola — used for gold and silver; 1 tola = 11.6638 g.
  • Quintal — used for crops and grain; 1 quintal = 100 kg.
  • Land units like bigha, katha and decimal have their own tool: the land area converter.

Kitchen conversions (US measures)

Many online recipes use US cups and spoons:

MeasureMillilitres
1 teaspoonabout 5 ml
1 tablespoonabout 15 ml
1 cupabout 237 ml
1 fluid ounceabout 30 ml

Indian kitchens often use a 200 ml or 250 ml cup, which differs from the US cup, so check which one a recipe means. Weights such as grams and ounces are more reliable for baking than cups.

Who uses a unit converter

  • Students solving physics and maths problems.
  • Cooks converting cups and tablespoons from foreign recipes.
  • Travellers and drivers converting miles, kilometres and speeds.
  • Online shoppers checking sizes in inches and centimetres.

Frequently asked questions

How many centimetres are in an inch?

1 inch = 2.54 cm exactly, so 1 cm ≈ 0.3937 inch. To convert cm to inches, divide by 2.54.

How do I convert kg to pounds?

Multiply kilograms by about 2.2046. 1 pound is exactly 0.45359237 kg, so 70 kg ≈ 154.3 lb.

How do I convert Celsius to Fahrenheit?

°F = °C × 9 ÷ 5 + 32. So 37 °C (normal body temperature) = 98.6 °F, and 100 °C = 212 °F. At −40 the two scales are equal.

How much is one tola in grams?

One tola is 11.6638 grams (the traditional measure of 180 grains). It is still used when buying gold and silver in India.

Is 1 GB 1000 MB or 1024 MB?

Both are used. Storage makers use decimal units (1 GB = 1000 MB), while computers often count in binary units (1 GiB = 1024 MiB). That is why a ‘1 TB’ drive shows about 931 GB in some computers. The converter lists both.

How many square feet are in a square metre?

1 square metre ≈ 10.764 square feet. For land units such as bigha, katha and decimal, use the land area converter.
