Answer :
To convert units in the metric system, it's important to understand the basic relationships:
- 1 gram (g) = 1,000 milligrams (mg)
- 1 kilogram (kg) = 1,000 grams (g)
- 1 tonne (t) = 1,000 kilograms (kg)
Now, let's convert each item step by step:
[tex]3\ \text{mg} = 0.003\ \text{g}[/tex]
To convert milligrams to grams, divide by 1,000.
[tex]64.7\ \text{t} = 64,700\ \text{kg}[/tex]
To convert tonnes to kilograms, multiply by 1,000.
[tex]58\ \text{kg} = 58,000,000\ \text{mg}[/tex]
First, convert kilograms to grams by multiplying by 1,000, then convert grams to milligrams by multiplying by 1,000 again.
[tex]75\ \text{g} = 0.075\ \text{kg}[/tex]
To convert grams to kilograms, divide by 1,000.
[tex]28\ \text{g} = 28,000\ \text{mg}[/tex]
To convert grams to milligrams, multiply by 1,000.
[tex]320\ \text{g} = 0.00032\ \text{t}[/tex]
First, convert grams to kilograms by dividing by 1,000, and then kilograms to tonnes by dividing by 1,000.
[tex]0.03\ \text{kg} = 30\ \text{g}[/tex]
To convert kilograms to grams, multiply by 1,000.
[tex]84\ \text{kg} = 0.084\ \text{t}[/tex]
To convert kilograms to tonnes, divide by 1,000.
[tex]0.0002\ \text{t} = 200\ \text{g}[/tex]
First, convert tonnes to kilograms by multiplying by 1,000, then kilograms to grams.
[tex]1.492\ \text{mg} = 0.000001492\ \text{kg}[/tex]
Convert milligrams to grams then grams to kilograms.
[tex]89.3\ \text{kg} = 89,300,000\ \text{mg}[/tex]
First, convert kilograms to grams and then grams to milligrams.
[tex]49110763\ \text{mg} = 0.049110763\ \text{t}[/tex]
Convert milligrams to grams, then grams to kilograms, and finally kilograms to tonnes.
I hope this helps you understand how to convert between these units!
