No it is definitely not cold. I live in a cold climate, so I think it's just a little bit warm, but someone from a warmer climate would think it's cool.
ADDED: 15ºC = 59ºF - I leave you to decide if comfortable or not!
-23 degrees Celsius is colder than -15 degrees Celsius. The lower the temperature in degrees Celsius, the colder it is. Therefore, -23°C represents a greater degree of cold compared to -15°C.
60 degrees Celsius is relatively hot. To get an idea of the Celsius system, consider that: 0 degrees Celsius is where water freezes 20-25 degrees Celsius is room temperature 37 degrees Celsius is body temperature 100 degrees Celsius is where water boils
-15 degrees Celsius is 5 degrees Fahrenheit.
18 degrees Celsius is 64.5 degrees Fahrenheit or 291 kelvin. Not cold.
Cold, but above freezing. Two degrees Celsius is 35.6 degrees Fahrenheit.
very very cold!
264.15 degrees Kelvin is 15 degrees Celsius less than 6 degrees Celsius.
15 degrees Celsius below 0 is -15 degrees Celsius.
-23 degrees Celsius is colder than -15 degrees Celsius. The lower the temperature in degrees Celsius, the colder it is. Therefore, -23°C represents a greater degree of cold compared to -15°C.
15 degrees Fahrenheit = -9.4 degrees Celsius.
-15 degree Celsius is colder than -3 degrees Celsius.
-15 degrees celsius is 5 degrees fahrenheit.
5 degrees Celsius is colder than 15 degrees Celsius.
(-15) degrees Celsius = 258.15K
60 degrees Celsius is relatively hot. To get an idea of the Celsius system, consider that: 0 degrees Celsius is where water freezes 20-25 degrees Celsius is room temperature 37 degrees Celsius is body temperature 100 degrees Celsius is where water boils
15 degrees C
125 degrees Celsius = 257 degrees Fahrenheit (hot, not cold).
