Temperature Units

Celsius (°C)

Water freezes at 0°C and boils at 100°C at sea level. Used in most countries worldwide.

Fahrenheit (°F)

Water freezes at 32°F and boils at 212°F. Primarily used in the United States.

Kelvin (K)

Absolute thermodynamic scale where 0K is absolute zero. Used in scientific contexts.

Rankine (°R)

Absolute scale using Fahrenheit degrees. 0°R is absolute zero (-459.67°F).

Réaumur (°Ré)

Water freezes at 0°Ré and boils at 80°Ré. Historically used in parts of Europe.

Reference Points

Unit	Absolute Zero	Freezing Point	Boiling Point

A Temperature Converter is a tool that converts temperature measurements between different units, such as Celsius (°C), Fahrenheit (°F), and Kelvin (K). Temperature is a fundamental physical quantity used in weather forecasting, cooking, science, engineering, and daily life.

Common Temperature Units

1. Celsius (°C)

• Used in: Most countries (Metric system), weather reports, cooking.

• Key Points:

  • 0°C = Freezing point of water

  • 100°C = Boiling point of water (at sea level)

2. Fahrenheit (°F)

• Used in: United States, some Caribbean countries.

• Key Points:

  • 32°F = Freezing point of water

  • 212°F = Boiling point of water

3. Kelvin (K)

• Used in: Scientific research, physics, thermodynamics.

• Key Points:

  • 0 K = Absolute zero (-273.15°C)

  • No negative values (theoretical minimum temperature)

Conversion Formulas

From	To	Formula
Celsius (°C)	Fahrenheit (°F)	$\mathrm{°}F=(\mathrm{°}C\times \frac{9}{5})+32$
Fahrenheit (°F)	Celsius (°C)	$\mathrm{°}C=(\mathrm{°}F-32)\times \frac{5}{9}$
Celsius (°C)	Kelvin (K)	$K=\mathrm{°}C+273.15$
Kelvin (K)	Celsius (°C)	$\mathrm{°}C=K-273.15$
Fahrenheit (°F)	Kelvin (K)	$K=(\mathrm{°}F-32)\times \frac{5}{9}+273.15$
Kelvin (K)	Fahrenheit (°F)	$\mathrm{°}F=(K-273.15)\times \frac{9}{5}+32$

Applications of Temperature Conversion

1. Weather Forecasting

• Converting between °C (used globally) and °F (used in the US).

2. Cooking & Baking

• Oven temperatures often differ by region (°F in the US vs. °C in Europe).

3. Science & Engineering

• Kelvin is used in physics, chemistry, and thermodynamics.

• Industrial processes requiring precise temperature control.

4. Medical Use

• Body temperature measurements (°F in the US, °C elsewhere).
