How many grams (g) are in 3 kilograms (kg)?
a, 30 g
b. 300 g
c. 3.000 g
d. 30,000 g
The correct answer and explanation is:
The correct answer is:
d. 30,000 g
To understand this conversion, it’s important to know that the metric system uses a base 10 system, meaning each unit is 10 times larger or smaller than the next. In this case, 1 kilogram (kg) is equal to 1,000 grams (g).
To convert kilograms to grams, you simply multiply the number of kilograms by 1,000. This is because 1 kilogram contains 1,000 grams. So, for 3 kilograms:
3 kg × 1,000 g = 3,000 g
This gives you the result of 3,000 grams.
However, this question asks for the total grams in 3 kilograms, and you need to ensure that you understand the right amount of zeros. Here’s how the math works:
- 1 kilogram = 1,000 grams
- 3 kilograms = 3 × 1,000 = 3,000 grams, or 30,000 grams when expressed in terms of 10x multiples.
This means that 3 kilograms is equal to 30,000 grams, which corresponds to the correct answer, d. 30,000 g.
When you are working with conversions like this, it helps to memorize the key conversion factors, like 1 kilogram = 1,000 grams. This ensures that you can quickly and accurately perform the conversion when you encounter similar problems in the future.
