About Temperature Scales
Temperature is a physical property that quantifies the degree of hotness or coldness of an object or environment.
Different temperature scales were developed throughout history:
- Celsius (°C): Created by Anders Celsius in 1742, setting 0°C as the freezing point of water and 100°C as the boiling point at standard atmospheric pressure.
- Fahrenheit (°F): Developed by Daniel Gabriel Fahrenheit in 1724, with 32°F as water's freezing point and 212°F as its boiling point at standard atmospheric pressure.
- Kelvin (K): Proposed by William Thomson (Lord Kelvin) in 1848, it's an absolute temperature scale with 0K representing absolute zero (no thermal energy). There are no negative Kelvin temperatures.
Conversion Formulas
The conversion between temperature units follows specific mathematical formulas.
Celsius to Fahrenheit
°F = (°C × 9/5) + 32
Celsius to Kelvin
K = °C + 273.15
Fahrenheit to Celsius
°C = (°F - 32) × 5/9
Fahrenheit to Kelvin
K = (°F - 32) × 5/9 + 273.15
Kelvin to Celsius
°C = K - 273.15
Kelvin to Fahrenheit
°F = (K - 273.15) × 9/5 + 32

Temperature Conversion Applications
Weather Forecasting
Converting between scales is essential for international weather reports and forecasts.
Cooking & Baking
Recipes from different countries often use different temperature scales for oven settings.
Scientific Research
Scientists often need to convert between scales when collaborating internationally or publishing research.
Travel
Travelers need to understand local temperature scales to dress appropriately and plan activities.
