SET 3: Question 1 of 12
How many µg are there in 6.5 mg?
Type in all zeros, eg 0.00000673
µg
There are 6500 mg in 6.5 µg.
1 µg = 10-6g
1 mg = 10-3g
Thus:
1 milligram is 10-3 times ie 103 imes larger than a microgram
10-6
Thus: 6.5 mg = 6.5 x 1000 mg = 6500 µg
No, that is not the correct answer.

SET 3: Question 2 of 12
How many ng are there in 2 mg?
Type in all zeros, eg 0.00000673
There are 2000000 ng in 2 mg.
1 ng = 10-9g
1 mg = 10-3g
1 milligram is 10-3 times ie 106 times larger than a nanogram
10-9
Thus: 2 mg = 2 x 1000000 ng = 2000000 ng
No, that is not the correct answer.

SET 3: Question 3 of 12
How many pg are there in 0.001 mg?
Type in all zeros, eg 0.00000673
There are 1000000 pg in 0.001 mg.
1 pg = 10-12g
1 mg = 10-3g
1 milligram is 10-3 times ie 109 times larger than a picogram.
10-12
Thus: 0.001 mg = 0.001 x 1 000 000 000 pg = 1 000 000 pg
No, that is not the correct answer.

SET 3: Question 4 of 12
How many mg are there in 550 µg?
Type in all zeros, eg 0.00000673
There are 0.55 mg in 550 µg.
1 mg = 10-3g
1 µg = 10-6g
Thus:
1 microgram is 10-3 times ie 103 times smaller than a milligram.
10-6
Thus: 550 µg = 550 / 1000 mg = 0.55 mg
No, that is not the correct answer.

Type in all zeros, eg 0.00000673
There are 0.001mg in 1000 ng.
1 mg = 10-3g
1 ng = 10-9g
1 nanogram is 10-3 times ie 106 times smaller than a milligram.
10-9
Thus: 1000 ng = 1000 / 1000000 mg = 0.001 mg
No, that is not the correct answer.

SET 3: Question 6 of 12
How many mg are there in 500 pg?
Type in all zeros, eg 0.00000673
There are 0.0000005 mg in 500 pg.
1 mg = 10-3g
1 pg = 10-12g
1 picogram is 10-3 times ie 109 times smaller than a milligram
10-12
Thus: 500 pg = 500 / 1 000 000 000 mg = 0.000 000 5 mg
No, that is not the correct answer.

SET 3: Question 7 of 12
How many ng are there in 10 µg?
Type in all zeros, eg 0.00000673
There are 10000 ng in 10 µg .
1 µg = 10-6g
1 ng = 10-9g
1 microgram is 10-6 times ie 103 times larger than a nanogram.
10-9
Thus: 10 µg = 10 x 1000 ng = 10000 ng
No, that is not the correct answer.

Type in all zeros, eg 0.00000673
There are 700000 pg in 0.7 µg.
1 µg = 10-6g
1 pg = 10-12g
Thus:
1 microgram is 10-6 times ie 106 times larger than a picogram
10-12
Thus: 0.7 µg = 0.7 x 1000000 pg = 700000 pg

There are 0.65 µg in 650 ng.
1 µg = 10-6g
1 ng = 10-9g
1 nanogram is 10-6 times ie 103 times smaller than a microgram.
10-9
Thus: 650 ng = 650 / 1000 µg = 0.65 µg
No, that is not the correct answer.

There are 0.0075 µg in 7500 pg.
1 µg = 10-6g
1 pg = 10-12g
Thus:
1 picogram is 10-6 times ie 106 times smaller than a microgram.
10-12
Thus: 7500 pg = 7500 / 1000000 µg = 0.0075 µg

Type in all zeros, eg 0.00000673
There are 2700 pg in 2.7 ng.
1 ng = 10-9g
1 pg = 10-12g
Thus:
1 nanogram is 10-9 times ie 10 3 times larger than a picogram.
10-12
Thus: 2.7 ng = 2.7 x 1000 pg = 2700 pg
