70 Celsius is equal to 343.15 kelvi.
The conversion from Celsius to kelvi involves adding 273.15 to the Celsius temperature. This shifts the scale from the freezing point of water at 0°C to absolute zero at 0 kelvi, allowing temperatures to be measured on an absolute scale.

Conversion Formula
The formula to convert Celsius (°C) to kelvi (K) is:
K = °C + 273.15
This formula works because Celsius scale sets 0°C at the freezing point of water, while kelvi scale starts from absolute zero, which is -273.15°C. Adding 273.15 shifts the Celsius value up to kelvi scale.
For example: To convert 70°C to kelvi:
- Start with 70°C
- Add 273.15 to it: 70 + 273.15 = 343.15
- The result is 343.15 kelvi
Conversion Example
- Convert 25°C to kelvi:
- Take 25°C
- Add 273.15: 25 + 273.15 = 298.15 K
- So, 25°C equals 298.15 kelvi
- Convert -10°C to kelvi:
- Begin with -10°C
- Add 273.15: -10 + 273.15 = 263.15 K
- Therefore, -10°C equals 263.15 kelvi
- Convert 0°C to kelvi:
- Start at 0°C
- Add 273.15: 0 + 273.15 = 273.15 K
- So, 0°C equals 273.15 kelvi
- Convert 100°C to kelvi:
- Take 100°C
- Add 273.15: 100 + 273.15 = 373.15 K
- 100°C equals 373.15 kelvi

Conversion Definitions
Celsius: Celsius is a temperature scale used to measure thermal energy, where 0°C marks the freezing point of water and 100°C marks its boiling point under standard atmospheric pressure. It is widely used in science and daily life for weather, cooking, and scientific experiments.
Kelvi: Kelvi is the SI base unit of temperature measurement, starting at absolute zero (0 K), the lowest possible temperature where particles have minimum thermal motion. It is used in physics and engineering to express temperatures on an absolute scale without negative values.
Conversion FAQs
Why do we add 273.15 to convert Celsius to kelvi?
Adding 273.15 shifts the Celsius scale, which starts at water freezing point, to kelvi scale that begins at absolute zero. Absolute zero is -273.15°C, so the addition aligns Celsius values with this absolute reference point, making kelvi always positive.
Can kelvi temperatures be negative like Celsius?
No, kelvi scale starts at absolute zero, the lowest possible temperature, so kelvi values cannot be negative. Celsius, however, has negative values below freezing point. This makes kelvi useful in scientific calculations where negative temperatures would be confusing.
Is the conversion exact or approximate?
The conversion by adding 273.15 is exact by definition of the scales. However, when rounding decimal values, slight differences can appear, but they are negligible for most practical purposes such as weather or engineering calculations.
Can I convert kelvi back to Celsius?
Yes, convert kelvi to Celsius by subtracting 273.15 from the kelvi temperature. This reverses the scale shift and gives the temperature in Celsius degrees.
Why is kelvi preferred in scientific measurements?
Kelvi is preferred because it starts at absolute zero, a fundamental physical limit. This makes calculations related to thermodynamics and physics simpler and more consistent, avoiding negative temperatures and simplifying formulas.
