distance
kilometers (km) are a measurement of length. Length cannot be measured by time unless there is an object moving.
The dimensions of a gym would best be measured in metres (m) and not kilometres (km).
== == Given that the circumference of the earth is 40,075.02 km (measured at the equator) the circumference in inches is roughly 1,577,756,664 inches.
Initial velocity can be measured in the same units as any other velocity. In SI, that would be meters per second, but often km / hour are used, or (in a minority of countries) feet/second or miles/hour.
distance
measured in Km
Some of them are.
If velocity is km/hr and time is in hours then acceleration will be in km/hr2
Lengths, distances and heights can be measured in kilometres (km) or metres (m). 1 m = 100 cm 1 km = 1000 m = 100 000 cm
Thickness of door is not measured in km. Kilometer is a big quantity.
The area of Singapore is 710.2km2.

Its a convenient length on a human scale.
Earths diameter is around 12,742 km on average. 12,756 km measured through the equator, 12,714 km measured from pole to pole. Earths mass is 5.9736 x 10 24 kg.
Square kilometres (sq km) is a measure of area not of length. So length cannot be measured in sq km.
