No, you are thinking of kilograms. Kilometers measures length or distance.
Kilometers is a measure of distance, not weight.
Weight
Weight; Weight = mg.
Sure. You can measure the weight of each of the objects, then subtract. Or you can put the objects on both sides of a pulley; this lets you directly measure the difference in weight.
weight of objects
The measure of the force of attraction between objects due to gravity is WEIGHT. ^_^
The objects weight is a measure of that force.
The objects weight is a measure of that force.
Kilometers measure length. Grams measure weight. One cannot be converted to the other.
Considering km is kilometers, a measure of distance and grams are a measure of weight, this would be difficult to answer. Did you mean kilometers to meters?
250 miles = 402.33600 kilometers. there is no such thing as "kiligrams" and kilograms are a measure of weight unlike kilometers which are a measure of distance or length.
A tool used to measure the mass (weight) of objects.
