The result of converting 23 Celsius to kelvin is 296.15 K.
To get this, you just add 273.15 to the Celsius value. Scientists and engineers use kelvin, because it starts from absolute zero, which is the coldest possible temperature. Celsius and kelvin have the same size degree, but their starting points are different. When you convert 23°C to kelvin, you get 296.15 K.

Conversion Formula
The formula for converting Celsius to kelvin is:
K = °C + 273.15
Celsius measures temperature based on water’s freezing and boiling points, at sea level. Kelvin starts at absolute zero, where all molecular motion stops. Since the interval between degrees is the same, only the starting point changes. You just add 273.15 to the Celsius value. This shifts the scale so zero kelvin is the lowest possible temperature.
Step-by-step calculation for 23°C to kelvin:
- Start with the Celsius value: 23
- Add 273.15 to 23: 23 + 273.15 = 296.15
- The result is 296.15 K
Conversion Example
-
Example 1: 0°C to kelvin
- Begin with 0
- Add 273.15: 0 + 273.15 = 273.15
- Answer: 273.15 K
-
Example 2: -10°C to kelvin
- Take -10
- Add 273.15: -10 + 273.15 = 263.15
- Kelvin value: 263.15 K
-
Example 3: 37°C to kelvin
- Start with 37
- Add 273.15: 37 + 273.15 = 310.15
- So, 37°C = 310.15 K
-
Example 4: 100°C to kelvin
- Start at 100
- Add 273.15: 100 + 273.15 = 373.15
- The answer’s 373.15 K

Conversion Definitions
Celsius: Celsius is a temperature scale where 0°C marks water’s freezing point, and 100°C is its boiling point at sea level. It’s used worldwide, except a few countries. The scale is based on dividing the range between these two points into 100 equal parts, each part is one degree.
Kelvin: Kelvin is an absolute temperature scale that starts at absolute zero, the lowest theoretical temperature. Zero kelvin (0 K) is when molecular motion is as close to none as possible. Each kelvin degree is equal in size to a Celsius degree, but the scale doesn’t use negative numbers.
Conversion FAQs
Why does kelvin use 273.15 as the offset from Celsius?
Kelvin is based on absolute zero, which is -273.15°C. Scientists picked this because at absolute zero, particles have almost no movement. The offset matches the difference between zero on both scales, making conversion easy by just adding 273.15.
Can kelvin values ever be negative?
No, kelvin doesn’t go below zero. Zero kelvin is the coldest possible temperature, it’s called absolute zero. You can’t have negative kelvin because you can’t go colder than particles not moving at all.
Why do researchers prefer kelvin for scientific work?
Kelvin’s absolute zero base makes calculations involving energy and physical laws simpler. Formulas in thermodynamics and physics use kelvin, since it avoids negative temperatures and matches the way energy changes are measured.
Is it correct to write “degrees kelvin”?
No, it’s not. Kelvin is not measured in degrees, just kelvin. You write “296.15 K” and not “296.15 degrees kelvin.” This avoids confusion and matches international standards.
How precise should kelvin conversions be recorded?
That depends what you need, but for scientific data, four decimal places is common. Some fields round to two places, but using at least two decimals helps avoid rounding errors, especially in lab measurements or calculations.
