One to one converters

Each box below is a small converter for one pair of units. Type in either side and the other changes.

How to convert a unit

Pick what you want to measure, such as length or weight. Type your number on the left and choose the unit you have. Choose the unit you want on the right and the answer shows at once. You can also type in the right box and the left box changes. Press the swap button to flip the two units.

Under the main box you see the same number in every other unit of that kind, so you do not have to change the unit again and again. Tap any box to copy it.

What you can convert

  • Everyday: length, weight, temperature, volume, area, speed and time.
  • Phone and computer: data size (MB, GB, TB) and internet speed (Mbps, MB/s).
  • Home and vehicle: pressure (psi, bar), energy (kWh, kcal), power (kW, horsepower), force, fuel economy (km/L, L/100 km, mpg).
  • Science and school: angle, frequency, density, torque.
  • Indian units: tola, seer, maund and quintal for weight; guntha, cent, kanal, marla and ground for land; lakh and crore for big numbers.

One to one converters

If you only need one thing, such as kilometres to miles or kilograms to pounds, use the one to one section. Each pair has its own small converter that works in both directions, so you do not need to choose anything. Press the arrow on a pair to open it in the full converter with every other unit.

Good to know

MB and MiB are not the same

Phone and hard disk makers count 1 MB as 1,000,000 bytes. Computers often count in steps of 1,024 and call it MiB. Both are in the list, so you can see the small difference. Internet speed in Mbps is in bits, and file size in MB is in bytes, so 100 Mbps is about 12.5 MB each second.

Land units change by state

A guntha is 1,089 square feet and a cent is about 435.6 square feet. Words such as bigha and kanal can mean different sizes in different states, so we only include the ones with a fixed size. Check your local land record if the number matters for a purchase.

Fuel economy goes the other way

More km/L is better, but fewer L/100 km is better. The converter handles this for you, so 20 km/L shows as 5 L/100 km.

Expert Answers

Frequently Asked Questions

Top questions about this tool.

Choose Length, type the number of kilometres and pick miles on the right. One kilometre is about 0.6214 miles, so 10 km is about 6.21 miles. You can also use the one to one box for kilometres to miles.
One tola is 11.6638 grams. Choose Weight and mass, set From to Tola and To to Gram. A tola of gold jewellery is usually counted as 10 grams in shops, so check with your jeweller.
MB counts 1,000,000 bytes and MiB counts 1,048,576 bytes. Storage makers use MB and GB, while many computer programs show MiB and GiB. That is why a new drive looks a little smaller on a computer.
Choose Temperature, type the degrees in Celsius and pick Fahrenheit. The rule is to multiply by 9, divide by 5 and add 32. For example, 30 degrees Celsius is 86 degrees Fahrenheit.
Yes. Choose Area and land. One acre is 40 guntha and 100 cent, and one guntha is 1,089 square feet. The converter also has kanal, marla, ground and the usual square feet and square metres.
One lakh is 100,000, which is 0.1 million. One crore is 10,000,000, which is 10 million. Choose Big numbers (Indian) to change between them.
Very big and very small answers are shown in short form. 1.5e+20 means 1.5 followed by 20 zeros. You can change the number of decimals above the results if you want a fixed format.
