23 °C = 296.15 K
In short
How many kelvin is 23 Celsius?
23 °C = 296.15 K. 1 Celsius = 1.000000 kelvin, then + 273.15, so the working is 23 × 1.000000 + 273.1500 = 296.15.
The working
The factor below is an exact definition rather than a measurement, so nothing is approximated in the arithmetic. The only rounding on this page happens where a number is displayed.
1 Celsius = 1.000000 kelvin, then + 273.15 23 × 1.000000 + 273.1500 = 296.15
How much precision do you need?
Each row is the same answer cut at a different number of decimals, with what that choice costs you. Pick the shortest row whose error is smaller than whatever you are measuring with.
| Rounded to | Answer (K) | Off by |
|---|---|---|
| Whole number | 296 | −0.15000 |
| 1 decimal | 296.1 | −0.05000 |
| 2 decimals | 296.15 | exact |
Round trip: take 296.15 K back the other way and you land on 23.0000 °C — a drift of 0.0000 °C. That gap is the rounding, not the conversion.

Frequently asked questions
What is 23 Celsius in kelvin?
23 Celsius is 296.15 kelvin. 1 Celsius = 1.000000 kelvin, then + 273.15, so the working is 23 × 1.000000 + 273.1500 = 296.15.
How accurate is 296.15 K?
Rounding to 296.15 K and converting straight back gives 23.0000 °C, a drift of 0.0000 °C from the 23 you started with. The factor itself is exact; every bit of that difference comes from the rounding, not the conversion.
