Quick guide
How to use this calculator
- Enter the value exactly as recorded, then choose its source unit and the unit you need.
- Check regional and technical qualifiers in the unit names. US and Imperial gallons, force and mass, absolute temperatures and temperature differences, and decimal and binary data prefixes are deliberately separate.
- Use the selected result first, then open the common-equivalents table when you need to compare several standards without re-entering the value.
Calculation method
How the temperature difference converter works
The entered temperature interval is converted once to the canonical kelvin basis and then from that basis to the selected output unit.
A temperature difference of 1 K equals 1 °C, while 1 °F difference equals 5/9 K.
Worked example
Temperature Difference example
A 10 °C temperature change equals an 18 °F change.
source value × source-to-kelvin relationship → canonical kelvin value → destination-unit relationship
Supported inputs
Precision and limits
Unit convention
A temperature difference of 1 K equals 1 °C, while 1 °F difference equals 5/9 K.
Precision
Definitions and exact conventional factors are retained internally where available. Display formatting uses up to 12 significant digits; very large or small results use scientific notation. Do not treat displayed digits as measurement accuracy beyond the source value.
Quantity boundary
This page converts temperature interval. It does not infer a different physical quantity, material property, environmental condition, exchange rate, calendar rule, or regulatory value needed to make a cross-quantity conversion.
Privacy
