Question

convert the following to si units: 3,000,000 grams
3,000 kg
3,000,000,000 mg
3,000,000 grams
3 mg

Explanation:

Step1: Recall SI - unit conversion for mass

The SI - unit of mass is the kilogram (kg). We know that 1 kg = 1000 g, 1 g=1000 mg, and 1 Mg (megagram)=1000000 g.

Step2: Convert 3000000 g to kg

Using the conversion factor 1 kg = 1000 g, we have $\frac{3000000}{1000}=3000$ kg.

Step3: Convert 3000000 g to mg

Using the conversion factor 1 g = 1000 mg, we have $3000000\times1000 = 3000000000$ mg.

Step4: Convert 3000000 g to Mg

Using the conversion factor 1 Mg=1000000 g, we have $\frac{3000000}{1000000}=3$ Mg.

Answer:

3000 kg, 3000000000 mg, 3000000 grams, 3 Mg are all correct conversions of 3000000 grams to different SI - related units. But if we consider the most common SI - base unit for mass among them, the answer is 3000 kg. So the answer is 3000 kg.
