Metres.
The unit of measurement for the quantity represented by the keyword "m unit" is meters (m).
The unit of measurement represented by the abbreviation "m" is meters.
145 km is a bigger unit. as 1 km=1000 m. 145 km= 145000m which is greater than 145 m.
we know that by unit and measurement we get that , 1 km =1000 m 1 m =0.001 km
The main unit of measurement for length is the meter (m).

The unit represented by the symbol "m" is meters, which is a unit of measurement for length in the metric system.
More or less... But not entirely. Here is an example: 1 km = 1000 meters. To convert from meters to kilometers, you can divide by 1000. However, you can just as well reason that, since 1 meter = 0.001 kilometers, you multiply by 0.001. The safest way to convert units is to multiply by a ratio that is equal to 1. In this example, you multiply a measurement either by (1 km / 1000 m), or by (1000 m / 1 km). Use whichever factor makes the unwanted unit disappear. For example, 500 m x (1 km / 1000 m) is using the correct factor, since the meters disappear. On the other hand, 500 m x (1000 m / 1 km) leaves you with units square meters / km, which is not the desired result.
The unit of measurement for linear acceleration is meters per second squared (m/s2).
The correct unit for speed in MKS system is 'm'.
1 km (kilometre) is 1000 times larger than 1 metre (m).
The kilogram is, which is 1000 times heavier.
