Temperature Converter

Type a number in Celsius, Fahrenheit, or Kelvin. The tool recalculates the other two fields. Use negative values freely for cold weather or cryogenic references. For oven temperatures, Fahrenheit and Celsius are most common; lab work often cites Kelvin for absolute thermodynamic calculations.

These are the standard linear relationships:

Kelvin starts at absolute zero (0 K). The size of one kelvin equals one Celsius degree, which is why the offset is exactly 273.15.

Many guidelines cite roughly 98.6 °F (37 °C) as average oral temperature, but normal varies by person, time of day, and measurement site. Always follow medical advice and use proper thermometers—not this tool—for health decisions.

US recipes often use °F; European ovens use °C. Convert the setpoint with this tool (e.g. 350 °F ≈ 177 °C). Fan-assisted ovens may need slightly lower settings per manufacturer guidance—that adjustment is not a pure unit conversion.

No. A step of 1 °C equals 1.8 °F because the Fahrenheit degree is smaller. A step of 1 K equals 1 °C. That is why slope factors 9/5 and 5/9 appear in the formulas.

• Travel: Interpret a foreign weather forecast in the units you are used to.
• Studying: Check homework when a problem states °C and the answer key uses °F.
• 3D printing / materials: Compare datasheet glass-transition or nozzle temperatures listed in different units.
