When the temperature when degree Celsius is equal to degree Fahrenheit

Click For Summary
SUMMARY

The discussion focuses on the mathematical relationship between Celsius (C) and Fahrenheit (F) temperatures, specifically when C equals F. The equation C = (F - 32) × 5/9 can be rearranged to find the point where the two scales intersect. By substituting C with F, the equation simplifies to F = (F - 32) × 9/5, leading to the conclusion that the temperature at which Celsius equals Fahrenheit is -40 degrees.

We need to solve for it when C= F.

so replace C with F or F with C in the equation and solve for it.
