-15 degrees Fahrenheit is approximately -26 degrees Celsius.
-15
15 degrees Fahrenheit is approximately -9.4 degrees Celsius. You can convert Fahrenheit to Celsius by subtracting 32, then multiplying by 5/9.
The freezing point of water is 0 degrees Celsius. Therefore, 15 degrees Celsius above the freezing point would be 15 + 0 = 15 degrees Celsius.
7 degrees Celsius is warmer than 3.5 degrees Celsius.
15 degrees Celsius is warmer than 3 degrees Celsius.

In the Celsius scale (as well as in other currently used temperature scales), a larger number indicates a warmer temperature.
-3 Celsius is warmer than -15 Celsius.
They are about the same because 60 degrees Fahrenheit is equivalent to 15.56 degrees Celsius
I suggest you convert each of the Fahrenheit temperatures to Celsius (or the other way round, each of the Celsius temperatures to Fahrenheit), and then compare.
Sound travels faster in warmer temperatures. At 30 degrees Celsius, sound will travel faster than at 15 degrees Celsius. This is because sound travels faster in warmer air due to the higher average speed of air molecules.
15 degrees Fahrenheit = -9.4 degrees Celsius.
To convert Celsius to Kelvin, simply add 273. So, 15 degrees Celsius is equivalent to 288 Kelvin (15 + 273).
