Length describes how long a thing is from one end to the other. The International System of Units, the SI, is the system of units in which. The distance covered by a vehicle (for example as recorded by an odometer), person, animal, or object along a curved path from a point A to a point B should be distinguished from the straight line distance from A to B. For Example,the length of an object = 40 cm. The rate or spring constant, k, relates the force to the extension in SI units: N/m or kg/s2. b 1)Both a meter and a kilometer are SI units. A. (speed) = (distance)a (time)b So in terms of units (ms−1) = (m)a (s)b 7. If n1 and n2 are the numerical values of a physical quantity corresponding to the units u1 and u2, then n1u1 = n2u2.
