Final answer:
Temperature scales like Celsius and Fahrenheit are measured using the interval scale.
Step-by-step explanation:
Temperature scales like Celsius (C) and Fahrenheit (F) are measured by using the interval scale. In both temperature measurements, 40° is equal to 100° minus 60°. Differences make sense. But 0 degrees does not because, in both scales, 0 is not the absolute lowest temperature. Temperatures like -10 °F and -15 °C exist and are colder than 0.
