The result of converting 7.5 c to k is 280.65 k.
To find the kelvin equivalent of 7.5 degrees Celsius, you just add 273.15 to the Celsius value. This method, it shifts the temperature scale up so all kelvin values stay positive, which is useful in science. The kelvin scale is absolute zero-based, so it never goes negative, unlike Celsius.

Conversion Formula
To convert a temperature in Celsius (c) to kelvin (k), you have to use this formula: k = c + 273.15. The Celsius scale is based on the freezing point (0°C) and boiling point (100°C) of water. The kelvin scale starts at absolute zero – the lowest possible temperature, where molecular energy is almost gone. That’s at -273.15°C. By adding 273.15 to a Celsius temperature, you shift it up to the kelvin scale.
Step-by-step calculation for 7.5 c to k:
- Write the formula: k = c + 273.15
- Substitute the value: k = 7.5 + 273.15
- Add the numbers: 7.5 + 273.15 = 280.65
- So, 7.5 c = 280.65 k
Conversion Example
- Example 1: Convert -10 c to k
- Write the equation: k = c + 273.15
- Plug in -10 for c: k = -10 + 273.15
- Add: -10 + 273.15 = 263.15
- Final answer: -10 c = 263.15 k
- Example 2: 0 c to k
- k = 0 + 273.15
- k = 273.15
- 0 c is 273.15 k
- Example 3: 25 c to k
- k = 25 + 273.15
- k = 298.15
- So, 25 c = 298.15 k
- Example 4: 100 c to k
- k = 100 + 273.15
- k = 373.15
- 100 c to k is 373.15 k

Conversion Definitions
c: Celsius (symbol: c) is a metric unit for measuring temperature, based on the freezing (0°) and boiling (100°) points of water at one atmosphere. Used in most countries for weather, cooking, and science, Celsius is part of the International System of Units for temperature.
k: Kelvin (symbol: k) is the standard SI unit for absolute temperature. It starts at absolute zero, the lowest temperature possible, equal to -273.15°C. One kelvin is the same size as one Celsius degree, but kelvin never goes below zero. Used for physics, chemistry, and engineering.
Conversion FAQs
Is kelvin temperature ever negative when converting from Celsius?
No, kelvin temperatures never go negative, because the scale starts at absolute zero. If you plug in a Celsius value lower than -273.15, the math gives you negative kelvin, but in reality that’s not possible, physically. Absolute zero is the lowest, so kelvin can’t drop under zero.
Why does the conversion add exactly 273.15?
273.15 is the difference between the Celsius zero point (freezing of water) and absolute zero. Scientists determined absolute zero is -273.15°C, so by adding 273.15, you shift any Celsius temperature to where zero kelvin means zero energy. That decimal is precise, not rounded.
Is it okay to round kelvin values after converting from Celsius?
In some cases, yes, rounding is fine. For everyday things like weather, rounding to the nearest kelvin won’t make much difference. But in lab experiments, physics, or chemistry, using all decimal places is better to keep calculations accurate, or you might get wrong results.
Can you use negative Celsius values in the formula?
Yes, the formula works for negative Celsius temperatures too. Just add 273.15, even if your Celsius number is below zero. The result will still be a positive kelvin, unless you try a number lower than -273.15, which is outside the real physical range for temperature.
