Temperature Converters

About Temperature Units

Temperature measures the average kinetic energy of particles in a substance. The metric system uses two temperature scales: Celsius for everyday use and Kelvin for scientific applications.

• Celsius (°C): Named after Anders Celsius, this scale sets water's freezing point at 0°C and boiling point at 100°C at standard pressure. Used worldwide for weather, cooking, and daily temperature measurements.
• Kelvin (K): One of the seven SI base units, named after Lord Kelvin. It's an absolute temperature scale starting at absolute zero (0 K = -273.15°C), where all molecular motion theoretically stops. Essential for scientific work.

Conversion Formula

Converting between Celsius and Kelvin is straightforward:

• Celsius to Kelvin: K = °C + 273.15
• Kelvin to Celsius: °C = K - 273.15

Common Temperature Reference Points

Description	Celsius (°C)	Kelvin (K)
Absolute Zero	-273.15°C	0 K
Water Freezing Point	0°C	273.15 K
Room Temperature	20°C	293.15 K
Human Body Temperature	37°C	310.15 K
Water Boiling Point	100°C	373.15 K

Temperature conversions are crucial in physics, chemistry, meteorology, and engineering. Celsius is practical for everyday life, while Kelvin is essential for thermodynamics and scientific calculations where absolute temperature matters.
