Final answer:
Fahrenheit (°F) is associated with the English system of temperature measurement, where 32 °F is the freezing point and 212 °F is the boiling point of water. It's one of three main temperature scales, alongside Celsius (°C) and Kelvin (K).
Step-by-step explanation:
The unit Fahrenheit (°F) is part of the temperature measurement system primarily used within the English system of measurement. In the Fahrenheit scale, the freezing point of water is set at 32 °F and the boiling point at 212 °F. This temperature scale is widely used in the United States for weather forecasts, cooking, and other applications. A relationship exists between the Fahrenheit scale and the Celsius scale, commonly used in many other parts of the world. The Celsius scale, on the other hand, designates 0 °C as the freezing point of water and 100 °C as the boiling point.
There are three main temperature scales: the Fahrenheit, Celsius, and Kelvin scales. The Celsius and Fahrenheit scales are both incremental scales, with the unit of degree used to describe the temperature increments. Kelvin is the base unit of temperature in the International System of Units (SI) and is an absolute temperature scale, which starts at absolute zero, the theoretical lowest possible temperature. Unlike Fahrenheit and Celsius, temperatures in the Kelvin scale are not referred to by 'degrees' but simply as kelvins (K).
