70 degrees Celsius is equal to 343.15 kelvin.
Table of Contents
To convert 70 degrees Celsius to kelvin, you add 273.15 to the Celsius temperature because kelvin scale begins at absolute zero, which is -273.15°C. This way, 0 kelvin represents absolute zero, so any Celsius value shifted by this amount gives the kelvin equivalent.

Conversion Formula
The formula to convert degrees Celsius to kelvin is:
K = °C + 273.15
This formula works because kelvin scale is based on absolute zero, which is -273.15°C. So, when you add 273.15 to any Celsius temperature, you shift the scale to start from absolute zero. For example, 0°C equals 273.15 K, and 100°C equals 373.15 K.
Step-by-step example for 70°C:
- Start with the Celsius value: 70
- Add 273.15: 70 + 273.15
- Result is 343.15 kelvin
Conversion Example
- Convert 25°C to kelvin:
- Take the Celsius value: 25
- Add 273.15: 25 + 273.15 = 298.15 K
- Convert -10°C to kelvin:
- Celsius is negative, so: -10 + 273.15
- Result: 263.15 K
- Convert 0°C to kelvin:
- 0 + 273.15 = 273.15 K
- Convert 100°C to kelvin:
- 100 + 273.15 = 373.15 K
- Convert 50.5°C to kelvin:
- 50.5 + 273.15 = 323.65 K

Conversion Definitions
Degrees: Degrees are units used to measure temperature on scales such as Celsius and Fahrenheit. In Celsius, degrees represent increments relative to the freezing point (0°C) and boiling point (100°C) of water under standard atmospheric conditions. This unit allows quantifying hotness or coldness.
Kelvin: Kelvin is an absolute temperature scale used in scientific contexts, starting at absolute zero where particles have minimum thermal motion. Unlike Celsius, kelvin has no negative values, making it useful for calculations involving thermodynamics and physics, measured in units equal to degrees Celsius increments.
Conversion FAQs
Why do we add 273.15 to convert Celsius to kelvin?
Adding 273.15 shifts the Celsius scale to start from absolute zero, the coldest possible temperature where molecular motion stops. Since kelvin scale begins at absolute zero, this addition adjusts the Celsius value to match kelvin’s starting point.
Can kelvin values be negative?
No, kelvin values cannot be negative because zero kelvin represents absolute zero, the lowest limit of temperature. Temperatures below this are physically impossible in current scientific understanding.
Is the kelvin scale used outside science?
Kelvin is mostly used in scientific and engineering fields where precise temperature measurements are needed. Everyday temperature readings use Celsius or Fahrenheit, but kelvin provides a universal scale for thermodynamics.
Does converting kelvin back to Celsius require subtracting 273.15?
Yes, to convert kelvin to degrees Celsius, you subtract 273.15 from the kelvin value. This reverses the initial offset used in the conversion.
Why is absolute zero exactly -273.15°C?
Absolute zero is defined by physics as the temperature where particles have minimal energy and motion, experimentally determined to be -273.15°C. This precise value sets the zero point for the kelvin scale.
