Answer key: Weight worksheet

1. In micrograms: 5,669,904,625 µg
1. Change to kilograms. Each oz is 0.0283495231 kg, so multiply by that
  $200 oz \times 0.0283495231$ $= 5.669904625 kg$
2. Change to micrograms. Each µg is 0.000000001 kg, so divide by that
  $\frac{5.669904625 kg}{0.000000001}$ $= 5,669,904,625 µg$
2. In pounds: 11.25 lb
1. Change to kilograms. Each oz is 0.0283495231 kg, so multiply by that
  $180 oz \times 0.0283495231$ $= 5.1029141625 kg$
2. Change to pounds. Each lb is 0.45359237 kg, so divide by that
  $\frac{5.1029141625 kg}{0.45359237}$ $= 11.25 lb$
3. In kilograms: 1.2e-4 kg
1. Change to kilograms. Each mg is 0.000001 kg, so multiply by that
  $120 mg \times 0.000001$ $= 0.00012 kg$
4. In stones: 15.75 st
1. Change to stones. Each st is 6.35029318 kg, so divide by that
  $\frac{100 kg}{6.35029318}$ $= 15.7473044418 st$
5. In stones: 0.58 st
1. Change to kilograms. Each oz is 0.0283495231 kg, so multiply by that
  $130 oz \times 0.0283495231$ $= 3.6854380063 kg$
2. Change to stones. Each st is 6.35029318 kg, so divide by that
  $\frac{3.6854380063 kg}{6.35029318}$ $= 0.5803571429 st$
6. In grams: 1,143,052.77 g
1. Change to kilograms. Each st is 6.35029318 kg, so multiply by that
  $180 st \times 6.35029318$ $= 1,143.0527724 kg$
2. Change to grams. Each g is 0.001 kg, so divide by that
  $\frac{1,143.0527724 kg}{0.001}$ $= 1,143,052.7724000001 g$
7. In stones: 0.02 st
1. Change to kilograms. Each g is 0.001 kg, so multiply by that
  $120 g \times 0.001$ $= 0.12 kg$
2. Change to stones. Each st is 6.35029318 kg, so divide by that
  $\frac{0.12 kg}{6.35029318}$ $= 0.0188967653 st$
8. In pounds: 2.73e-4 lb
1. Change to kilograms. Each mg is 0.000001 kg, so multiply by that
  $124 mg \times 0.000001$ $= 0.000124 kg$
2. Change to pounds. Each lb is 0.45359237 kg, so divide by that
  $\frac{0.000124 kg}{0.45359237}$ $= 0.0002733732 lb$
9. In us short tons: 5.62e-3 short tn
1. Change to kilograms. Each oz is 0.0283495231 kg, so multiply by that
  $180 oz \times 0.0283495231$ $= 5.1029141625 kg$
2. Change to us short tons. Each short tn is 907.18474 kg, so divide by that
  $\frac{5.1029141625 kg}{907.18474}$ $= 0.005625 short tn$
10. In pounds: 4.96 lb
1. Change to kilograms. Each dag is 0.01 kg, so multiply by that
  $225 dag \times 0.01$ $= 2.25 kg$
2. Change to pounds. Each lb is 0.45359237 kg, so divide by that
  $\frac{2.25 kg}{0.45359237}$ $= 4.9604008992 lb$
