What are the most commonly used unit conversions?

The most searched unit conversions are kg to lbs, cm to inches, miles to km, Celsius to Fahrenheit, and MB to GB. All of these are available as one-click presets in the popular conversions bar above. Click any pill to load that conversion instantly without navigating menus.

Length and weight conversions dominate search volume because the US uses imperial units while most of the world uses metric. Temperature conversions are common for weather and cooking. Data storage conversions are increasingly searched as file sizes grow. The developer tab covers bits vs bytes, which is a common point of confusion for people comparing internet speeds (Mbps) to file sizes (MB). For a deeper reference, see the unit conversion guide.

How do you convert Celsius to Fahrenheit?

Multiply Celsius by 9, divide by 5, then add 32. The formula is F = (C x 9/5) + 32. For example, 20 degrees Celsius equals 68 degrees Fahrenheit. To reverse it, subtract 32 then multiply by 5/9.

A quick mental shortcut: double the Celsius temperature and add 30 for a rough Fahrenheit estimate. This gives 20C = 70F (actual: 68F), close enough for everyday use. The converter above shows the exact formula and result for any temperature you enter. The same formula display works for all other unit types, showing exactly what multiplication or division factor was applied. For working with structured data alongside conversions, the JSON formatter and regex tester are useful companion tools.

What is the difference between MB and GB?

1 GB equals 1,024 MB in binary measurement (used by operating systems) or exactly 1,000 MB in decimal measurement (used by storage manufacturers). This difference is why a 1 TB hard drive shows as about 931 GB in Windows, which uses binary.

Internet speeds are measured in megabits per second (Mbps), not megabytes. To convert download speed to file transfer rate, divide Mbps by 8. A 100 Mbps connection downloads files at about 12.5 MB per second. The developer tab above handles bits vs bytes conversions instantly, using binary factors (1 KB = 1,024 bytes) to match what your operating system reports.

Frequently asked questions about unit conversion

How many centimeters are in an inch?
There are exactly 2.54 centimeters in one inch. To convert inches to centimeters, multiply by 2.54. To convert centimeters to inches, divide by 2.54 or multiply by 0.3937.
How do I convert kg to lbs?
Multiply kilograms by 2.20462 to get pounds. For example, 70 kg equals 154.32 lbs. To convert lbs to kg, divide by 2.20462 or multiply by 0.453592.
How do I convert Celsius to Fahrenheit?
Use the formula F = (C x 9/5) + 32. For example, 25 degrees Celsius equals 77 degrees Fahrenheit. To convert Fahrenheit to Celsius, use C = (F - 32) x 5/9.
How many MB is 1 GB?
1 GB equals 1,024 MB in binary (base-2) measurement used by computers, or exactly 1,000 MB in decimal (SI) measurement used by storage manufacturers. Most operating systems use binary, so a 1 GB file takes 1,024 MB of storage.
How many kilometers are in a mile?
1 mile equals exactly 1.60934 kilometers. To convert miles to kilometers, multiply by 1.60934. To convert kilometers to miles, divide by 1.60934 or multiply by 0.621371.
How do I convert ounces to grams?
Multiply ounces by 28.3495 to get grams. For example, 8 oz equals 226.8 grams. To convert grams to ounces, divide by 28.3495 or multiply by 0.035274.
What is the difference between bits and bytes?
1 byte equals 8 bits. Internet speeds are measured in bits per second (Mbps), while file sizes are measured in bytes (MB). A 100 Mbps connection transfers 12.5 MB per second because 100 divided by 8 equals 12.5.
How many feet are in a meter?
1 meter equals 3.28084 feet. To convert meters to feet, multiply by 3.28084. To convert feet to meters, divide by 3.28084 or multiply by 0.3048.
How do I convert speed from mph to km/h?
Multiply mph by 1.60934 to get km/h. For example, 60 mph equals 96.56 km/h. To convert km/h to mph, divide by 1.60934 or multiply by 0.621371.
What is a hexadecimal number and how do I convert it?
Hexadecimal (hex) is a base-16 number system using digits 0-9 and letters A-F. Hex FF equals decimal 255. Use the developer conversions tab above to convert between decimal, binary, hexadecimal, and octal instantly.
