Remember K H D | d c m. Kilograms is three places to the left of grams. So you have to move the decimal place three times to the left. So in this case the answer is 6.005 kilograms.
6 grams plus 3 kilograms equals 3,006 grams
K = 1,000 grams 0.454 + 46 = 46.454 = 0.046454K
3 kilograms is equal to 3000 grams, so when you add 3000 grams and 125 grams together, you get a total of 3125 grams.
3006 grams
6,0005. Grams
Expressed in grams, this is equal to 870 + 590 = 1460 grams. Expressed in kilograms, this is equal to 1.46 kilograms.
4003.2 grams 1 kilogram = 1000 grams 1 gram = 0.001 kilograms
1 Kilogram = 1000 grams. You now have all the necessary information to work out the answer.
Making the assumption that by 1700, you mean 1700 grams, your answer will be 1.7 kg + 3.8 kg + 4.3 kg - Which equals 9.8 kilograms.
There are 1000 grams in one kilogram. Therefore, 2.7 kilograms is equal to 2.7 x 1000 = 2700 grams. Adding this to 600 and 250 gives us 2700 + 600 + 250 = 3550 grams.
To add it all up, convert kilograms to grams (multiplying by 1000), or convert the grams to kilograms (dividing by 1000). "On the Moon" is irrelevant; the mass will be the same almost anywhere in the Universe.
There are 1000 grams in one kilogram. Therefore, 9.75 kilograms is equal to 9.75 x 1000 = 9750 grams. Adding 756 grams to this gives 9750 + 756 = 10506 grams or 10.506 kilograms.
