Missing question:
0.0854 kilogram
85.4 grams
8.54 hectograms
85,400 milligrams.
Answer is: 8.54 hectograms is not the same.
1 cg = 0.01 g; one centigram is equal to 10⁻² grams.
m = 8540 cg.
m = 8540 cg · 0.01 g/cg.
m = 85.4 g.
1) m = 0.0854 kg.
1 kg = 1000 g.
m = 0.0854 kg · 1000 g/kg.
m = 85.4 g; it is the same.
2) m = 85.4 g; it is the same.
3) m = 8.54 hg.
1 hg = 100 g; one hectogram is 100 grams.
m = 8.54 hg · 100 g/hg.
m = 854 g; it is not the same.
4) m = 85400 mg.
1 mg = 0.001 g.
m = 85400 mg · 0.001 g/mg.
m = 85.4 g; it is the same.
