To convert a temperature from degrees Celsius to Kelvin, you can use the simple formula:
K = C + 273.15
In this case, you want to convert 45 degrees Celsius to Kelvin. So, you would plug 45 into the formula:
K = 45 + 273.15
This gives you:
K = 318.15
Therefore, 45 degrees Celsius is equal to 318.15 Kelvin.
This conversion is essential in science and engineering, where temperature measurements in Kelvin are often required for calculations and experiments.
