Celsius
📖 Celsius (°C) is a unit of temperature on the Celsius scale, also known as the centigrade scale. It is commonly used in scientific and everyday contexts for measuring temperature.
💡 Did you know that the Celsius scale was originally defined based on the freezing and boiling points of water? 0°C represents the freezing point of water, while 100°C represents the boiling point at sea level. It's a scale deeply rooted in the properties of one of our most essential resources.
Fahrenheit
📖 Fahrenheit (°F) is a temperature scale primarily used in the United States. It is based on the freezing and boiling points of water, but with a different zero point and increment compared to Celsius or Kelvin.
💡 Ever wonder how Fahrenheit got its name? The scale was developed by Daniel Gabriel Fahrenheit, a Polish-German physicist, in the early 18th century. He invented the mercury-in-glass thermometer and introduced this scale, which is still commonly used in the United States today.
