Supported Temperature Units

Unit Symbol Common Uses Key Fact
Celsius °C Most countries worldwide, scientific work Water freezes at 0°C and boils at 100°C
Fahrenheit °F United States, some Caribbean nations Water freezes at 32°F and boils at 212°F
Kelvin K Scientific research, absolute temperature 0K is absolute zero (-273.15°C)
Rankine °R Engineering systems (US) Fahrenheit equivalent of Kelvin scale

Temperature Conversion Tips

1

For quick Fahrenheit to Celsius estimation: Subtract 30 then halve (100°F ≈ (100-30)/2 = 35°C)

2

Remember that -40° is the same in both Fahrenheit and Celsius scales

3

Kelvin temperatures are always positive numbers (absolute zero is 0K)

4

For scientific work, always specify which temperature scale you're using

Temperature Conversion FAQs

Different temperature scales were developed for various purposes. Fahrenheit was created in the early 18th century using brine solutions as reference points. Celsius was developed later with water's freezing and boiling points as references. Kelvin was established in the 19th century for scientific work requiring absolute temperature measurements.

All temperature scales can be equally accurate as they're just different ways to measure the same physical property. Kelvin is often preferred in scientific work because it starts at absolute zero and its degrees are the same size as Celsius degrees, making calculations involving temperature changes more straightforward.

The conversion formula works the same for negative temperatures: °F = (°C × 9/5) + 32. For example, -10°C converts to (-10 × 9/5) + 32 = (-18) + 32 = 14°F. Our converter handles all negative values automatically with perfect accuracy.

The Kelvin scale is an absolute temperature scale where 0K represents absolute zero (the theoretical absence of all thermal energy). Unlike Celsius and Fahrenheit which are relative scales, Kelvin measures absolute temperature, so it doesn't use the degree symbol. It's simply written as "273 K" not "273°K".
