Question

The mass of an object is 100 mg. What is the object's mass in kg?

Answer 1

0.0001 is the objects mass because you go from mili, to centi, deci, gram, deca, hecta, Kila. that's 6 decimal points which is what times you 3 zeroes before the 1. The decimal point started out at the end of 100 and moved 6 places to be 0.0001

Answer 2

100 mg is equal to 0.0001 kg

Step-by-step explanation:

When doing conversions, you always need to remember the units you are working with. So when going from mg to kg, there are a lot of zeros to take into consideration.

1. mg to g:

When converting from milligrams to grams, you divide by 1000, because there are 1000 milligrams in 1 gram.

100 milligrams is equal to (100 ÷ 1000) grams

= 0.1 grams

2. Then converting g to kg:

When converting grams to kilograms, you once again divide by 1000, because there are 1000 grams in 1 kilogram.

0.1 grams is equal to (0.1 ÷ 1000) kilograms

= 0.0001 kilograms
