| Unit | Value |
|---|---|
| Celsius (°C) | 37 |
| Fahrenheit (°F) | 98.6 |
| Kelvin (K) | 310.15 |
| Rankine (°R) | 558.27 |
What this calculator does
Temperature scales differ in both size of degree and zero point, so conversions are not simple multiplications.
Formula and method
K = °C + 273.15; °F = °C × 9/5 + 32; °R = K × 9/5
Worked example
Calculated by this tool with its default inputs:
Inputs
- Value: 37
- From: Celsius (°C)
- To: Fahrenheit (°F)
Results
- 37 °C in °F: 98.6 °F
- Conversion type: Exact (from defined constants; display rounded to 12 significant figures)
How to read the results
−40 is the same on the Celsius and Fahrenheit scales.
Assumptions and limitations
- Values below absolute zero (0 K) are rejected.
- This converts temperatures, not temperature differences — a change of 1 °C equals a change of 1.8 °F.
- Constants follow NIST SP 811 and the SI Brochure. Conversions marked exact follow from defined values; display is rounded to 12 significant figures.
