Question

How many tons are equal to 6.87 x 10 9mg? (1 oz = 28.34 g, 1 ton = 2000 lb)

Answer 1

To convert 6.87 x 10^9 mg to tons, first convert mg to g, then g to lb, and finally lb to tons using the given conversion factors.

Step-by-step explanation:

To convert milligrams (mg) to tons, we need to use the given conversion factors:

1 milligram (mg) = 0.001 gram (g)

1 gram (g) = 0.002205 pound (lb)

1 ton = 2000 pounds (lb)

First, convert the milligrams to grams by multiplying by the conversion factor:

6.87 x 109 mg * (0.001 g / 1 mg) = 6.87 x 106 g

Then, convert the grams to pounds by multiplying by the conversion factor:

6.87 x 106 g * (0.002205 lb / 1 g) = 15153.87 lb

Finally, convert the pounds to tons by dividing by the conversion factor:

15153.87 lb / 2000 lb = 7.577 tons (rounded to three decimal places)
