The temperature at which the Celsius and Fahrenheit scales read the same is -40°. This means that both scales indicate -40° at that point.
Understanding Temperature Scales
Celsius and Fahrenheit are two different systems for measuring temperature. They have different zero points and increments, which is why they can show the same value at specific points.
Answer Choices Analysis
- A. -40° - This is the correct answer.
- B. +40° - This is not the same on both scales.
- C. -80° - This does not match either scale.
- D. -20° - This is also different on both scales.
In summary, the only temperature where Celsius and Fahrenheit are equal is -40°.
