Final answer:
Fahrenheit and Celsius meet at -40 degrees, where both scales show the same numerical value for temperature.
Step-by-step explanation:
The Fahrenheit and Celsius temperature scales meet at a specific point where they display the same numerical value for a given temperature. This occurs at -40 degrees, where -40°F is equivalent to -40°C. To understand this crossover point, one must recognize that the Fahrenheit scale defines the freezing point of water at 32°F and the boiling point at 212°F, whereas the Celsius scale defines those points at 0°C and 100°C respectively. A degree Celsius is 1.8 times as large as a degree Fahrenheit, meaning the scales converge at -40 degrees, where the differences in scale and starting points cancel each other out.
