Question

1 mg is equal to 10-3 hg. 103 dg. 10-3 g. 10-2g.

Answer 1

The correct answer is C.
`10^(-3)`g

Step-by-step explanation:

A milligram (mg) is a unit for measuring mass in the same way that grams or kilograms; however, the milligram is one of the smallest units of this kind. In terms of equivalence, the milligram can be equivalent to other mass units including the kilogram (kg), the hectogram (hg), the decigram (dg) and the gram (g). Indeed 1 mg is equivalent to 0,000001 kg or
`10^(-6)` kg; also it is equivalent to 0,00001 dg or
`10^(-5)`, to 0,001 g. or
`10^(-3)` g. or to 0,01 dg or
`10^(-2)`. Thus, the option that shows the correct equivalence of 1 mg is
`10^(3)` g because a milligram is equivalent to 0.001 grames.

Answer 2

1 mg is equal to 10-3 gram.

1 gram is equal to 1000 milligrams

1 milligram (1 gram / 1000 milligram) = 1 x 10^-3 or 10^-3 gram
