Answer to Question #48129 in Other Engineering for ashfaq
what is physical quantities ?
Solution: A physical quantity is a physical property that can be quantified by measurement. Examples: If the temperature T of a body is quantified (measured) as 300 degrees Kelvin this is written, where T is the symbol of the physical quantity (NB degrees Celsius cannot be treated in this way) If a person weighs 120 pounds, then "120" is the numerical value and "pound" is the unit. This physical quantity mass would be written as "120 lbs"
