Celsius to Kelvin — °C to K Converter

Conversion Formula

Plug the Celsius value into the temperature formula below.
K = C + 273.15

How to Convert Step by Step

• Enter the number of Celsius you want to convert (e.g. 30 °C).
• Multiply it by the factor given in the formula (or apply the temperature formula).
• Round the result to 2–4 decimals for practical use — done, that is your value in Kelvin.

Common Celsius to K Conversion Table

Real-World Examples

• Celsius is used for weather, body temperature (normal ≈ 36–37°C), and oven settings. Example: 30 °C ≈ 303.15 K.
• Kelvin is used in physics, astronomy, and engineering — room temperature ≈ 293 K, Sun's surface ≈ 5778 K. Example: 37 K ≈ -223.15 °C.
• Celsius is used for weather, body temperature (normal ≈ 36–37°C), and oven settings. Another common case: 50 °C = 323.15 K.

About Celsius & Kelvin

• Celsius: Celsius was introduced by Anders Celsius in 1742: 0°C = water freezing, 100°C = boiling. It is the world's most used scale.
• Kelvin: Kelvin starts at absolute zero: 0 K = −273.15°C. It is the SI thermodynamic temperature scale used in science.
• Watch significant figures: 2–3 decimals are enough for daily use; keep more for engineering and science.

FAQ

How many Kelvin in 1 °C?

1 °C = 274.15 K. Use the converter above to compute any value, or multiply °C by the temperature formula.

Is this Celsius-to-Kelvin converter accurate?

Yes — conversions use the standard temperature formulas (e.g. F = C × 9/5 + 32), and results are rounded to 4 decimals.

When is Celsius to Kelvin conversion used?

Celsius is used for weather, body temperature (normal ≈ 36–37°C), and oven settings. Kelvin is used in physics, astronomy, and engineering — room temperature ≈ 293 K, Sun's surface ≈ 5778 K. Whenever a value is given in °C but you need K, this converter is the quick fix.
