This is a very simple request, and the most straightforward interpretation is that you're asking for a representation of a temperature.
Since you provided just "1", and didn't specify a unit, I'll give you the most common interpretations:
1 Degree Celsius (°C) 1 Degree Fahrenheit (°F)
If you had a specific context in mind (e.g., "what is the temperature of boiling water?"), please provide more information!
