At what temperature are Celsius and Fahrenheit equal?

The temperature at which the Celsius and Fahrenheit scales are equal is -40 degrees. This means that -40°C is the same as -40°F.

Understanding the Conversion

To see why this is the case, you can use the formula for converting Celsius to Fahrenheit:

• F = (C × 9/5) + 32

Finding the Point of Equality

To find the temperature where both scales match, set F equal to C:

• -40 = (-40 × 9/5) + 32

When you solve this equation, you will find that both temperatures indeed equal -40.

Practical Implications

This point of equality is interesting because it shows how different temperature scales can intersect, even though they are based on different reference points. Understanding this can help in various fields, including science and everyday life.
