About temperature scales

Temperature scales mix ratios and offsets. Kelvin (K) is absolute; Celsius (°C) and Fahrenheit (°F) are offset scales.

Browse common units in this category and learn where they are typically used.

Celsius (°C) (celsius)
Celsius (°C) is an offset scale where 0 °C marks water’s freezing point and 100 °C its boiling point at 1 atm. Widely used worldwide.
Fahrenheit (°F) (fahrenheit)
Fahrenheit (°F) is an offset scale with 32 °F as freezing point and 212 °F as boiling point. Still used in the US and some Caribbean nations.
Kelvin (K) (kelvin)
Kelvin (K) is the SI base unit of temperature, measuring absolute thermodynamic temperature starting from absolute zero.
Rankine (°R) (rankine)
Temperature unit used in specific engineering or scientific contexts (e.g. Rankine).

Start with some of the most frequently used conversions in this category.

Offsets matter: °F = (°C × 9/5) + 32, K = °C + 273.15.

Temperature conversions are affine (ratio + offset), not pure ratios.

Open a few ready-made examples for common real-world conversions.

Is temperature conversion exact?

Temperature conversions use exact affine formulas (ratio + offset).

Can I share a specific result?

Yes. Every converter has a clean, shareable URL like /convert/meter-to-foot/2.5.
