About the Temperature Converter
What is the Temperature Converter?
Temperature scales have different zero points, so conversion needs both a multiplier and an offset. This temperature converter applies them for you.
Enter a reading in any scale to see it in Celsius, Fahrenheit, Kelvin and Rankine.
How to use the Temperature Converter
- Temperature (sample: 37)
- From (sample: Celsius (°C))
- To (sample: Fahrenheit (°F))
- Press Convert Temperature (results also refresh as you type). The result card shows the Converted Temperature, along with Celsius, Fahrenheit, Kelvin and Rankine.
Formula used
°F = °C × 9/5 + 32; K = °C + 273.15; °R = K × 9/5
- °C = Celsius
- °F = Fahrenheit
- K = Kelvin (absolute)
- °R = Rankine (absolute, Fahrenheit-sized degrees)
Temperatures below absolute zero (0 K) are rejected.
Worked example
These are the sample values already filled in the calculator above, and the result it returns for them:
| Input | Sample value |
|---|---|
| Temperature | 37 |
| From | Celsius (°C) |
| To | Fahrenheit (°F) |
| Result | Value |
|---|---|
| Converted Temperature | 98.6°F |
| Celsius | 37°C |
| Fahrenheit | 98.6°F |
| Kelvin | 310.15 K |
| Rankine | 558.27°R |
Tips for using the Temperature Converter
- Quick estimate: double the Celsius value and add 30 to get approximate Fahrenheit.
- −40 is the same in Celsius and Fahrenheit.
