Interpretation:
The unit that does not represent an SI base unit should be selected.
Concept introduction:
The most widely used modern form of the metric system for measurements is said to be an international system of units (SI Units), that contains a system of unit measurement based on seven base units. The seven base units are Kelvin, second, meter, ampere, kilogram, candela, and mole.
Answer to Problem 1STP
The correct option is (c), degree Celsius.
Explanation of Solution
Reason for correct option:
The degree Celsius is the unit for temperature.
The SI base unit for temperature is Kelvin not degree Celsius so, the unit that does not represent an SI base unit is degree Celsius. The unit degree Celsius can be converted to Kelvin or vice-versa.
Reason for incorrect options:
Second, kilogram and meter are units of time, mass and length respectively, and these are among the standard units of measurements defined by SI.
