Unit definition
Celsius (°C) Water freezes at 0 °C at standard pressure.
Unit history
The scale is named for Anders Celsius; its modern definition is tied to the kelvin with an exact offset of 273.15.
Step by step
1. Parse the value, including fractions.
2. Convert °C to kelvin.
3. Convert the base value to °F and apply your display precision.
Understand the result before using it
Temperature changes a temperature reading between Celsius, Fahrenheit, kelvin, and Rankine using the required scale offsets. The numerical value changes because the size and definition of the selected unit changes; the underlying quantity does not.
Calculated result
The conversion follows the displayed unit relationship. Display rounding can hide additional digits, and measured inputs cannot become more accurate merely by changing units.
Formula, assumptions, and example
Formula
Convert °C to kelvin, then convert the base value to °F.
Assumptions
- The source and target selections represent the same physical quantity or supported notation.
- The entered value is valid for the selected relationship and uses the source unit shown.
- Published unit definitions and conventional conversion factors apply under their stated conditions.
Worked example
0 °C equals 32 °F.
When to use it
Good uses
- Translate a temperature value found in a document, specification, recipe, or measurement.
- Compare values reported in different unit systems.
- Check a manual conversion and control the displayed precision.
Limitations
Common mistakes to avoid
- Temperature scales use offsets as well as scale factors, so a simple multiply-or-divide shortcut is not generally valid.
- Do not add meaningful digits beyond the precision of the original measurement.
- Confirm regulated, safety-critical, laboratory, and contractual values against the controlling standard.

Questions about this calculation
What does the Temperature converter do?
Temperature changes a temperature reading between Celsius, Fahrenheit, kelvin, and Rankine using the required scale offsets. It does not change the physical quantity represented by the input.
What formula does the Temperature converter use?
Convert °C to kelvin, then convert the base value to °F.
Why can a Temperature converter result be rounded?
UnitMora calculates with JavaScript double-precision numbers, then formats the result using your selected decimal or significant-figure setting. The unrounded value may contain more digits than are displayed.
What is the most common temperature conversion mistake?
Temperature scales use offsets as well as scale factors, so a simple multiply-or-divide shortcut is not generally valid.
