The temperature 80 degrees Celsius is equal to 353.15 kelvin.
To convert Celsius to kelvin, you add 273.15 because kelvin starts at absolute zero, which is -273.15°C. So, 80°C plus 273.15 gives the kelvin value. This makes it easy to change between these two temperature scales.

Conversion Formula
The formula to convert Celsius to kelvin is simple: K = °C + 273.15
This works because the kelvin scale starts at absolute zero, which is -273.15°C. So, when you add 273.15, you shift the Celsius temperature up to start from zero kelvin. For example, if the temperature is 80°C:
- Start with 80°C
- Add 273.15 to it: 80 + 273.15
- Result is 353.15 K
This way, the scales align correctly for scientific calculations requiring absolute temperature.
Conversion Example
- Convert 25°C to kelvin:
- Take 25°C
- Add 273.15 → 25 + 273.15 = 298.15 K
- So, 25°C equals 298.15 kelvin
- Convert -10°C to kelvin:
- Start with -10°C
- Add 273.15 → -10 + 273.15 = 263.15 K
- Negative Celsius values still become positive kelvin
- Convert 100°C to kelvin:
- 100 + 273.15 = 373.15 K
- The boiling point of water in kelvin
- Convert 0°C to kelvin:
- 0 + 273.15 = 273.15 K
- Freezing point of water on kelvin scale

Conversion Definitions
Celsius: Celsius is a temperature scale used worldwide, where 0 degrees is freezing point of water and 100 degrees is boiling point at sea level. It measures temperature based on the metric system and is commonly used in weather reports, science, and daily life.
Kelvin: Kelvin is the SI unit for temperature, starting at absolute zero (0 K), where all thermal motion ceases. It uses the same increment size as Celsius but shifted so that 0 K equals -273.15°C. Kelvin is preferred in science for thermodynamic temperature measurements.
Conversion FAQs
Why do we add 273.15 instead of 273?
The exact offset between Celsius and kelvin scales is 273.15, not a rounded 273. This decimal ensures precise conversion since kelvin starts exactly at -273.15°C, accurate for scientific calculations where small differences matter.
Can kelvin temperatures be negative?
No, kelvin is an absolute scale beginning at absolute zero, which is 0 K. Temperatures below zero kelvin don’t exist in classical thermodynamics because that would imply less than no thermal energy.
Is 80°C a high temperature in kelvin terms?
In kelvin, 80°C equals 353.15 K, which is moderate temperature common in many heating processes or warm climates, but far from extreme temperatures like boiling water at 373.15 K or higher.
Do I need to convert Celsius to kelvin for everyday use?
For most daily activities, Celsius is enough. Kelvin is mostly used in scientific fields, physics, and engineering where absolute temperature measurement matters more than relative temperature.
How precise is the Celsius to kelvin conversion?
The conversion is exact with the 273.15 offset. The precision depends on the number of decimal places you use, but for practical purposes, four decimal places like 353.1500 K is sufficiently precise.
