Fahrenheit invented the mercury thermometer in 1714, but it is unknown exactly how many he made. It divided the freezing and boiling points of water into 180 degrees. 32Â°F was the freezing point of water and 212Â°F was the boiling point of water, set by Fahrenheit himself. 0Â°F was based on the temperature of an equal mixture of water, ice, and salt. Fahrenheit based his scale on the temperature of the human body.
Fahrenheit had invented an alcohol thermometer in 1709 prior to unveiling its mercury counterpart, which proved to be more accurate. Ten years later, he unveiled his namesake Fahrenheit scale, which divided the freezing and boiling points of water into 180 degrees.
