70 degrees Celsius is equal to 343.15 kelvin.
The conversion from degrees Celsius to kelvin involves adding 273.15 to the Celsius temperature. This is because kelvin is an absolute temperature scale starting at absolute zero, while Celsius sets zero at the freezing point of water. By shifting the scale, we get the temperature in kelvin.

Conversion Formula
The formula to convert Celsius degrees to kelvin is:
K = °C + 273.15
This formula works because the kelvin scale is based on absolute zero, the lowest possible temperature, which is −273.15°C. By adding 273.15 to any Celsius temperature, you shift the scale so that 0 K equals -273.15°C, thus converting the temperature into kelvin.
For example, to convert 70°C:
- Start with 70°C
- Add 273.15 to 70: 70 + 273.15 = 343.15 K
- The result is 343.15 kelvin
Conversion Example
- Convert 25°C to kelvin:
- Take 25°C
- Add 273.15: 25 + 273.15 = 298.15 K
- Result: 298.15 kelvin
- Convert -10°C to kelvin:
- Start with -10°C
- Add 273.15: -10 + 273.15 = 263.15 K
- Resulting temperature is 263.15 kelvin
- Convert 100°C to kelvin:
- 100°C plus 273.15: 100 + 273.15 = 373.15 K
- The answer is 373.15 kelvin
- Convert 0°C to kelvin:
- 0 + 273.15 = 273.15 K
- This equals 273.15 kelvin

Conversion Definitions
Degrees: A unit of measure for temperature on various scales like Celsius and Fahrenheit. Degrees Celsius measure temperature relative to freezing and boiling points of water at sea level. Degree values indicate how hot or cold an object or environment is in relation to these reference points.
Kelvin: The base unit of temperature in the International System, kelvin is used in science and engineering. It starts at absolute zero, the coldest possible temperature where particle motion stops. Kelvin scale doesn’t use degrees but simply kelvin units, making it absolute and non-negative.
Conversion FAQs
Why do we add exactly 273.15 to convert Celsius to kelvin?
Because zero kelvin is absolute zero, which equals −273.15°C. Adding 273.15 shifts the Celsius scale so that the point of absolute zero corresponds to 0 K, making the scales aligned properly for scientific calculations.
Can kelvin values be negative?
No, kelvin temperatures cannot be negative. The kelvin scale starts at absolute zero, where molecular motion theoretically stops. Negative values would imply temperatures below absolute zero, which are not physically possible.
Is 70 kelvin the same as 70 degrees Celsius?
No, 70 kelvin is much colder than 70 degrees Celsius. Since 0°C equals 273.15 K, 70 K corresponds to about -203.15°C, so these two numbers represent very different temperatures.
How precise is the 273.15 value in conversions?
The 273.15 is exact by definition for the freezing point of water on the Celsius scale relative to kelvin. For most practical uses, this precision is sufficient, but scientific studies may use more decimal places if required.
Does this conversion apply to Fahrenheit degrees too?
No, Fahrenheit uses a different scale and must first be converted to Celsius before converting to kelvin. Fahrenheit to Celsius involves subtracting 32 and then multiplying by 5/9 before adding 273.15 for kelvin.
