## Explain the Difference Between Fahrenheit and Celsius Scale The Fahrenheit and Celsius scales are two different systems of temperature measurement. The main difference lies in the reference points and the size of the degree divisions on each scale.

Fahrenheit Scale:

• Developed by physicist Daniel Gabriel Fahrenheit in the early 18th century.
• The Fahrenheit scale uses the freezing and boiling points of water as its reference points.
• Water freezes at 32 degrees Fahrenheit (32°F).
• Water boils at 212 degrees Fahrenheit (212°F) at sea level.
• The Fahrenheit scale has 180 equal divisions between the freezing and boiling points of water.
• To convert temperatures between Fahrenheit and Celsius, you can use the formula:
• Celsius = (Fahrenheit – 32) × 5/9
• Fahrenheit = Celsius × 9/5 + 32

Celsius Scale:

• Developed by Swedish astronomer Anders Celsius in the mid-18th century.
• The Celsius scale uses the freezing and boiling points of water as its reference points as well.
• Water freezes at 0 degrees Celsius (0°C).
• Water boils at 100 degrees Celsius (100°C) at sea level.
• The Celsius scale has 100 equal divisions between the freezing and boiling points of water.
• The Celsius scale is widely used in most countries around the world, particularly in scientific and metric systems.

The Fahrenheit and Celsius scales differ in their reference points and the size of degree divisions. While Fahrenheit is commonly used in the United States and a few other countries, Celsius is the standard scale in most parts of the world. Converting between the two scales requires the use of conversion formulas, as mentioned above.
