Express the following in kilograms.
a. 190g
b. 247g
c. 44 kg 80 g
The correct answer and explanation is:
To convert grams to kilograms, you divide the value in grams by 1000 because there are 1000 grams in one kilogram. The formula for conversion is: Kilograms=Grams1000\text{Kilograms} = \frac{\text{Grams}}{1000}
a. 190g to kilograms:
To convert 190 grams to kilograms, divide 190 by 1000: 190g=1901000=0.19 kg190g = \frac{190}{1000} = 0.19 \, \text{kg}
So, 190 grams is equal to 0.19 kilograms.
b. 247g to kilograms:
Similarly, for 247 grams: 247g=2471000=0.247 kg247g = \frac{247}{1000} = 0.247 \, \text{kg}
Therefore, 247 grams is equal to 0.247 kilograms.
c. 44 kg 80g to kilograms:
This one is a bit more involved because you have both kilograms and grams. First, convert the 80 grams to kilograms: 80g=801000=0.08 kg80g = \frac{80}{1000} = 0.08 \, \text{kg}
Now, add this to the 44 kilograms: 44 kg+0.08 kg=44.08 kg44 \, \text{kg} + 0.08 \, \text{kg} = 44.08 \, \text{kg}
So, 44 kg 80g is equal to 44.08 kilograms.
Conclusion:
- 190 grams = 0.19 kilograms
- 247 grams = 0.247 kilograms
- 44 kg 80g = 44.08 kilograms
Understanding how to convert grams to kilograms is essential when working with various units of mass. In scientific contexts or everyday scenarios, kilograms are often preferred because they represent a larger quantity, making them more convenient for measuring things like body weight, groceries, or large objects. Conversion between grams and kilograms helps maintain consistency in measurements, especially when dealing with both large and small values.
