About Fahrenheit
Fahrenheit (°F) was developed by German physicist Daniel Gabriel Fahrenheit in 1724 and remains the primary temperature scale in the United States, Belize, and the Cayman Islands. Water freezes at 32°F and boils at 212°F at standard atmospheric pressure. For Americans, common references include: room temperature (68-72°F), body temperature (98.6°F), and a hot summer day (90-100°F). The scale was originally based on the lowest temperature Fahrenheit could create with ice and salt (-17.8°C or 0°F).
About Celsius
Celsius (°C) is the most widely used temperature scale worldwide, named after Swedish astronomer Anders Celsius (1742). It's based on the freezing point of water at 0°C and boiling point at 100°C under standard atmospheric pressure (1 atmosphere). This makes it intuitive for daily use: room temperature is around 20-22°C, body temperature is 37°C, and a hot summer day might reach 35-40°C. It's the standard in science, medicine, and weather reporting in most countries.
