UNITS AND DIMENSIONS
3 QUANTITY ADOPTED AS Z A STANDARD OF MEASUREMENT
UNITS OF MASS,LENGTH AND TIME THEY ARE FUNDAMENTAL BECAUSE: 3 1. Well defined and independent to each other Independent of physical conditions 3. Can be easily expressed in their terms raised to various powers
3 THE UNITS OF PHYSICAL QUANTITIES WHICH DERIVED FROMM FUNDAMENTAL UNITS OF LENGTH, MASS AND TIME.
3 FIXED AND REAL VALUE OF ANY PHYSICAL QUANTITYIS INVERSELY PROPORTIONAL TO ITS NUMERICAL VALUE,i.e or
1. Must be universal of proper size and magnitude. 3 2. Must not be affected by variations in temperature, pressure and time RS O3. Should be easily definable and reproducible
