Samantha NicoleThe result of converting 23 Celsius to Kelvin is 296.15 kelvin.
To convert Celsius to Kelvin, you add 273.15 to your Celsius value. This is because zero Kelvin is defined as absolute zero, which is -273.15°C. So, 23°C plus 273.15 equals 296.15 K. This method works for any Celsius temperature you have.

Conversion Formula
The formula for converting Celsius to Kelvin is straightforward. You take the Celsius temperature and add 273.15. This is because the Kelvin scale start at absolute zero, which is exactly -273.15°C. So, you shift the scale up by 273.15 units. The formula looks like this: K = °C + 273.15.
For example, to convert 23°C to Kelvin:
- Start with the Celsius value: 23°C
- Add 273.15 to that: 23 + 273.15 = 296.15
- The answer is 296.15 K
This formula works for negative Celsius values too, just add 273.15 regardless of the sign.
Conversion Example
- 10°C to Kelvin:
- Take 10°C.
- Add 273.15 which is the constant: 10 + 273.15
- Result: 283.15 K
- -5°C to Kelvin:
- Start with -5°C.
- Add 273.15: -5 + 273.15
- Result: 268.15 K
- 37°C to Kelvin:
- Use 37°C.
- Add 273.15: 37 + 273.15
- Result: 310.15 K
- 0°C to Kelvin:
- Start with 0°C.
- Add 273.15: 0 + 273.15
- Result: 273.15 K
- 48°C to Kelvin:
- Begin with 48°C.
- Add 273.15: 48 + 273.15
- Result: 321.15 K

Conversion Definitions
Celsius: Celsius is a temperature scale, used worldwide for everyday temperature measurement. It is based on the freezing point of water at 0°C and boiling point at 100°C under standard conditions. Temperatures below zero are possible, and it is used in weather, science, and cooking.
Kelvin: Kelvin is an absolute temperature scale, starting at absolute zero, which is the coldest possible temperature, 0 K. It does not use degree symbols. Each kelvin is the same size as a degree Celsius, but the two scales offset by 273.15. It is used in scientific and engineering calculations.
Conversion FAQs
Do you ever get negative values in kelvin when converting from celsius?
No, the kelvin scale starts at absolute zero, 0 K, so it never goes negative. When converting negative Celsius values, like -300°C, the result still will not go below zero on the kelvin scale.
Why do scientists prefer kelvin for temperature measurements?
Kelvin is preferred in science because it begins at absolute zero, making calculations about energy and particle motion more logical. The kelvin scale helps formulas work without negative numbers, which are confusing in physical chemistry and physics.
Is there a degree sign for kelvin like there is for Celsius?
No, kelvin never uses the degree symbol. It is just written as K, not °K. Writing “degrees kelvin” is considered wrong by scientists, they only use “kelvin” for this scale.
How precise does the conversion from Celsius to kelvin need to be?
Precision depends how you use the result. For school lessons, rounding to two decimals is usually okay, but in laboratory settings, more decimal places is often needed to ensure accuracy in experiments or calculations.
Does the conversion formula change if you measure at high pressures?
The conversion formula between Celsius and kelvin does not change, even at high or low pressures. The offset of 273.15 is based on the definition of the scales, not physical conditions, so the math stays the same in all settings.
