The result of converting 7.5 c (Celsius) to k (Kelvin) is 280.65 K.
To get this result, you add 273.15 to the Celsius temperature. This is because the Kelvin scale starts at absolute zero, which is -273.15°C. So, every degree in Celsius is equivalent to the same increment in Kelvin, but with a different starting point. This method ensures direct and accurate conversions between these temperature scales.

Conversion Formula
The formula to convert Celsius to Kelvin is simple: K = C + 273.15. Both scales have increments of one degree, but Kelvin starts from absolute zero, while Celsius starts from the freezing point of water. The formula shifts the starting point, making calculation quick.
Here’s how it works with 7.5°C:
- Start with the Celsius temperature: 7.5.
- Add 273.15 to it: 7.5 + 273.15.
- This gives 280.65.
- So, 7.5°C equals 280.65 K.
This method is reliable for all real-world temperatures, except for extremely high or low hypothetical values, which don’t usually appear in daily life.
Conversion Example
- Example 1: Convert -10°C to K
- Start with -10.
- Add 273.15: -10 + 273.15 = 263.15.
- So, -10°C equals 263.15 K.
- Example 2: Convert 0°C to K
- Take 0.
- Add 273.15: 0 + 273.15 = 273.15.
- 0°C is 273.15 K.
- Example 3: Convert 25°C to K
- Begin with 25.
- Add 273.15: 25 + 273.15 = 298.15.
- Result: 298.15 K.
- Example 4: Convert 100°C to K
- Start with 100.
- Add 273.15: 100 + 273.15 = 373.15.
- So, 100°C is 373.15 K.

Conversion Definitions
c (Celsius): Celsius is a scale for temperature where 0° marks the freezing point of water, and 100° sets the boiling point at standard atmospheric pressure. It is used worldwide, and values can be negative or positive, depending on the context. Celsius is abbreviated as “°C”.
k (Kelvin): Kelvin is an absolute temperature scale, starting at absolute zero, which is the lowest limit where molecular motion stops. There are no negative values in Kelvin. One Kelvin increase is equal to one Celsius degree, but the scale begins at 0 K, equivalent to -273.15°C. Kelvin is used in science.
Conversion FAQs
Does converting Celsius to Kelvin affect the size of a degree?
No, the size of a degree doesn’t change when going from Celsius to Kelvin. Both scales increase by the same amount for each degree. The only difference is the zero point, which is shifted by 273.15 units.
Why can’t Kelvin temperatures be negative?
Kelvin starts at absolute zero, where all molecular motion theoretically stops. You can’t have less than zero motion, so Kelvin doesn’t include negative values on its scale, it’s physically impossible to reach below 0 K.
What is the practical use for converting Celsius to Kelvin?
Kelvin is used in science because it measures absolute temperature, which is needed for physics, chemistry, and thermodynamics. Many equations require temperature in Kelvin to work correctly, so scientists convert from Celsius for accuracy.
Is the offset always 273.15 when converting Celsius to Kelvin?
Yes, for all normal temperatures, you always add 273.15. This value was set by international agreement, and it stays the same no matter what temperature you’re working with.
Can you use the same formula for negative Celsius temperatures?
Yes, negative Celsius values are common in weather and science, and you still add 273.15 to convert them. For example, -20°C equals 253.15 K, so the formula works for any number, negative or positive.
