Temperature Converter
Quick answer
Convert °C and °F with the standard affine formulas; Kelvin adds an offset from absolute zero.
For a related estimate, see Length Converter.

Core logic
°F = °C × 9/5 + 32 · °C = (°F − 32) × 5/9 · K = °C + 273.15.

Temperature scales relate through affine maps (°C, °F, K): linear offsets plus scaling. Use it for weather, cooking, lab ranges, and HVAC setpoints.
How to use this calculator
- Set inputs: Pick the source scale and value.
- Pick units: Read the target scale from the tool.
- Verify: Note whether you need Kelvin for physics formulas.
Real-world examples
- Example: 25 °C → 77 °F. 32 °F → 0 °C.
- Round-trip check: Convert the result back to the starting unit—if you do not land near your original value within rounding, confirm you picked the right direction (e.g., A→B vs B→A).

Short explanation
Relative “twice as hot” language does not apply to °C/°F; compare differences or use Kelvin for ratios.
FAQ
Are these conversions exact?
Fixed definitions (e.g., inches to cm) are exact. Values that depend on standards or rounding may differ slightly by display precision.
Why pick this hub instead of a single pair page?
Pair pages target one direction and one jump; this hub page matches the multi-unit converter card where you can switch units freely.
How accurate is this calculator?
It applies standard math to the inputs you enter. Real lenders, payroll rules, and rounding can differ—use results for planning and comparison, not as binding quotes.
