Comprehension Measurement is an important aspect to express any physical quantity. The measurement may be a direct or indirect approach. But the accuracy in the measurement depends on the approach, instrument, observation and proper recording. The error that might creep in will get propagated to all the places and in all relations where we use this measured value. Irrespective of the system, the product of number and unit is a constant. The parallax of a distance object observed from two points across the diameter of our earth is 1( of an arc. If radius of earth is 6400 km, of the distance of the body is (1 A.U. = 1.5 × 108 km):
0.2 A.U
0.2 km
0.293 A.U.
1 A.U

The error that might creep in will get propagated to all the places and in all relations where we use this measured value. Irrespective of the system, the product of number and unit is a constant. As the value of number n in nu = constant is increased, the unit u will:
Be increased
Be decreased
Remain same
Increase according the system
