What is the efficiency of a device that gives you 10 units of useful energy for every 100 units you put in it?
0.10, or 10%
Why do you found it useful to have two units for the amount of substance the kilograms and the mole?
Actually, the kilogram and the mole measure two quite different things. The kilogram is a unit of mass. The mole is a unit of amount of substance, in the sense of the amount of atoms or molecules (in multiples of Avogadro's number). The same amount of kilograms can have varying amounts of moles, for different substances.
What is the input of energy for a device that provides 50 units of useful energy and has an efficiency of 0.55?
50 units = (0.55) x (the input)Divide each side of the equation by 0.55 :50 units/0.55 = (the input) = 90.91 units (rounded)

What are light years and astronomical most useful?
Units such as light years and astronomical units are useful because they can be used to measure very large distances without yielding extremely large numbers.
Why is it sometimes useful to use arbitrary units?
It is sometimes useful to use arbitrary units because it may take you too much time to figure out the logically ideal units to use, or you may not even know in which numerical range your results may fall.
SI units are useful because they are all related by multiples of?

Newtons are units to use when measuring?
One newton (N) is equal to the amount of force needed to move 1 kilogram of substance one centimeter per second. This unit of measure can be useful when measuring the amount of force medium to large sized objects experience.

Is 14000 greater or less than 7 kg?
The answer will depend on the units for 14000. But since you have not bothered to provide that crucial bit of information, I cannot provide a more useful answer.The answer will depend on the units for 14000.
