How To Use

Convert temperatures instantly between Celsius, Fahrenheit, and Kelvin. Perfect for cooking, weather, science, and international travel.

1

Enter the Temperature Value

Type or paste the temperature value you want to convert into the "Value" input field. You can enter whole numbers or decimals (e.g., 100, 37.5, -10).

2

Select Source Scale

Choose the temperature scale you're converting FROM using the "From" dropdown. Options include Celsius (°C), Fahrenheit (°F), and Kelvin (K).

3

Select Target Scale

Choose the temperature scale you want to convert TO using the "To" dropdown. The conversion happens automatically with the correct formula.

4

View Converted Temperature

See the converted temperature displayed prominently in the result box. The result updates in real-time as you type or change scales.

5

Swap Scales (Optional)

Click the swap button (⇄) to instantly reverse the conversion, swapping the "From" and "To" scales without re-entering the value.

Frequently Asked Questions

1 Why are temperature conversions different from other unit conversions?
Temperature conversions are non-linear because the zero points are different on each scale. Celsius and Fahrenheit have different zero points (0°C = 32°F), and Kelvin uses absolute zero (0K = -273.15°C). This requires special conversion formulas, not simple multiplication like length or weight conversions.
2 What is the formula for Celsius to Fahrenheit?
To convert Celsius to Fahrenheit: multiply by 9/5, then add 32. Formula: °F = (°C × 9/5) + 32. For example, 25°C = (25 × 9/5) + 32 = 45 + 32 = 77°F.
3 What is the formula for Fahrenheit to Celsius?
To convert Fahrenheit to Celsius: subtract 32, then multiply by 5/9. Formula: °C = (°F - 32) × 5/9. For example, 77°F = (77 - 32) × 5/9 = 45 × 5/9 = 25°C.
4 What is Kelvin and when is it used?
Kelvin (K) is the SI base unit for temperature, used primarily in scientific contexts. Absolute zero is 0K (-273.15°C). Kelvin = Celsius + 273.15. It's used in physics, chemistry, and engineering for calculations involving temperature differences and thermodynamic equations.
5 At what temperature do Celsius and Fahrenheit have the same value?
Celsius and Fahrenheit are equal at -40 degrees. That is, -40°C = -40°F. This is the only point where the two scales intersect.
6 Are the conversions stored?
No, all conversions happen locally in your browser. We don't store, save, or transmit any of your data. Your privacy is completely protected.
