There are degrees of accuracy, just as there are degrees of heat, or temperature.

Something can be accurate, or more accurate, or inaccurate (3.14 is an accurate approximation of 'pi', 3.1415 is more accurate, 3.1416 is even more accurate, 3 is less accurate, due to differing

*precisio*n. Then 10 is even so much less accurate that it rather deserves the term approximate (if even that), unless you are describing the number 'ten', and not 'pi'.

BTW, degrees of heat can be expressed in Celsius, or Kelvin, or Fahrenheit, or ..., either precisely or not.

Things like Hot or Cold are relative terms, everything is hot compared to absolute zero (0 Kelvin), although there is some scientific research that suggests that under some specific circumstances it is theoretically possible to reach ever colder temperatures.

The words 'accurate' and 'precise' are different beasts.
