The result of converting 7.5 c to k is 280.65 k.
When you convert 7.5 c (degrees Celsius) to k (Kelvin), you add 273.15 to the Celsius value. Kelvin is the SI base unit for temperature, starting at absolute zero. Celsius is offset by 273.15 from Kelvin, so this addition gives you the right value for scientific work.

Conversion Formula
The formula to change Celsius (c) into Kelvin (k) is: k = c + 273.15. This means, everytime you want to convert, just add 273.15 to your Celsius temperature. Celsius uses water’s freezing point as zero, but Kelvin’s zero is at absolute zero, the coldest possible temperature. The scale difference is exactly 273.15 units. That’s why we only need to add, not multiply or subtract anything else.
For 7.5 c to k, the math looks like this:
- Start with the Celsius value: 7.5
- Add 273.15: 7.5 + 273.15
- Result: 280.65 k
No extra steps or conversions, just this simple addition, makes the process fast but also reliable for science and engineering.
Conversion Example
-
Convert -10 c to k:
- Start with -10 c
- Add 273.15: -10 + 273.15 = 263.15 k
-
Convert 0 c to k:
- Start with 0 c
- Add 273.15: 0 + 273.15 = 273.15 k
-
Convert 25 c to k:
- Begin with 25 c
- Then add 273.15: 25 + 273.15 = 298.15 k
-
Convert 100 c to k:
- Take 100 c
- Add 273.15: 100 + 273.15 = 373.15 k
-
Convert -17.5 c to k:
- Start with -17.5 c
- Add 273.15: -17.5 + 273.15 = 255.65 k

Conversion Definitions
c (Celsius): Celsius is a temperature scale where zero degrees is the freezing point of water. The scale increments by one for each degree. Used by most countries, Celsius makes it easier to relate to daily weather, water boiling, and freezing points. Abbreviated as “c”.
k (Kelvin): Kelvin is the SI base unit for temperature, starting at absolute zero, where all particle motion stops. There are no negative Kelvin values. Each Kelvin degree is the same size as a Celsius degree. Used in science, physics and chemistry labs, written as “k”.
Conversion FAQs
Is it possible for Kelvin values to be negative when converting from Celsius?
No, Kelvin can’t be negative. Absolute zero (0 k) is the coldest temperature possible, so any Celsius value below -273.15 would give a non-physical negative Kelvin, which can’t happen in reality. Calculators may show it, but it’s not possible physically.
Do you always add 273.15 to convert any Celsius value to Kelvin?
Yes, always just add 273.15 to the Celsius value, whatever the number. The offset is fixed, so it never changes. This works for positive, negative, or zero Celsius values alike. There’s no need for complicated math or conversion factors.
Why is Kelvin preferred in science and engineering?
Kelvin starts at absolute zero, so calculations involving energy and thermodynamics are simpler. It avoids negative values, which makes scientific equations easier to handle. Celsius can be negative, which is confusing in some scenarios.
Is there any difference between a degree Celsius and a Kelvin change?
No, the size of one degree on the Celsius scale is exactly equal to one Kelvin. Only the starting point (zero) is different. A change of 10 c is the same as a change of 10 k, so temperature intervals are identical.
