kilograms because grams are smaller than kilograms.
You normally measure it in tonnes
Kilograms.
Kilograms, gram's would be to large of a number and you should always try to have the smallest number possible, that way when you hare your numbers with other people this makes it easier for people to remember the numbers, because they don't have this extremely large number for them to remember. Now depending on who your sharing your information with, I suggest that if your sharing with people that are not scientist or people that send their information outside of the country, use your native conversion's. (For example: In the U.S.A use pounds not kilograms that's not what we use.)
14000 lbs = 6350 kilograms (approx)

A cow has the weight of 90 kilograms

It depends on the size of the truck, and it could be more accurate if you measured it in tons.
The weight capacity of a truck load can vary based on the type of truck. On average, a standard truck can hold anywhere from 3,000 to 8,000 kilograms. Heavy-duty trucks can carry even higher loads, up to 20,000 kilograms or more.
Why is this filed under "Relationships"? And I believe it depends on your location. In the US it'd probably be tons, and in the UK it'd probably be kilograms.
Normally the MASS would be specified. Although this is informally called the weight, mass and weight are two quite different things. The mass of a garbage truck might be indicated in kilograms, or in tons (thousands of kilograms). The actual weight would be measured in Newtons.
