How the Unit Converter Works
This converter helps students, cooks, engineers and travelers switch between metric and imperial measurements across 10 categories: length, weight, temperature, area, volume, speed, time, digital storage, energy and pressure.
General Conversion Method
Output Value = Input Value ร (From Unit Factor รท To Unit Factor)
For every category except temperature, each unit has a fixed conversion factor relative to a base unit (for example, meters for length, grams for weight, liters for volume). Converting between any two units multiplies your value by the source unit's factor and divides by the target unit's factor.
Temperature Is Different
Temperature scales don't share a common zero point, so they can't use a simple multiplication factor. Instead, any value is first converted to Celsius (Fahrenheit: (ยฐF โ 32) ร 5/9; Kelvin: K โ 273.15), then converted from Celsius to the target scale (Fahrenheit: ยฐC ร 9/5 + 32; Kelvin: ยฐC + 273.15).
Unit Converter FAQs
How accurate are these unit conversions?
Conversions use standard internationally recognized conversion factors (such as 1 inch = 0.0254 meters exactly) and results are rounded to 6 decimal places, which is precise enough for virtually all everyday, academic and professional uses.
Why is temperature converted differently from other units?
Length, weight and most other units share a common zero point, so converting between them is a simple multiplication. Temperature scales (Celsius, Fahrenheit, Kelvin) have different zero points, so the calculator first normalizes any value to Celsius, then converts from Celsius to your target scale.
What's the difference between a metric ton and a US ton?
A metric ton (tonne) equals 1,000 kilograms (about 2,204.6 pounds), while a US ton (short ton) equals 2,000 pounds (about 907.185 kilograms). This converter treats them as distinct units so you get the correct figure for your region.
Can I convert digital storage units like GB to MB accurately?
Yes. Digital storage conversions here use binary (1024-based) multiples โ 1 kilobyte = 1024 bytes, 1 megabyte = 1024 kilobytes, and so on โ which matches how operating systems typically report file and drive sizes.
How do I quickly reverse a conversion?
Click the 'Swap Units' button to instantly swap your From and To units while keeping the same category, so you can see the conversion in the opposite direction without re-entering anything.
