About Temperature Scales
Temperature is a measure of the average kinetic energy of particles in a substance. The three most common scales are Celsius, Fahrenheit, and Kelvin. Celsius, used worldwide for everyday purposes, sets water's freezing point at 0° and boiling point at 100°. Fahrenheit, primarily used in the United States, sets these at 32° and 212° respectively. Kelvin is the SI unit for temperature in science, starting at absolute zero (the point where all molecular motion stops).
Key conversion formulas include: F = (C × 9/5) + 32, C = (F - 32) × 5/9, and K = C + 273.15. Understanding these relationships is essential for science, cooking, weather forecasting, and international travel.
Frequently Asked Questions
Multiply the Celsius temperature by 9/5 (or 1.8) and then add 32. The formula is: F = (C × 9/5) + 32. For example, 100°C = (100 × 1.8) + 32 = 212°F.
Subtract 32 from the Fahrenheit temperature and then multiply by 5/9. The formula is: C = (F - 32) × 5/9. For example, 72°F = (72 - 32) × 5/9 = 22.22°C.
Absolute zero is the lowest possible temperature. It is 0 Kelvin, -273.15°C, and -459.67°F. At this temperature, all molecular motion ceases.
Kelvin is primarily used in scientific contexts. It starts at absolute zero, making it ideal for physics and chemistry calculations. Celsius is better suited for everyday temperature measurements.
