What is the conversion of 6.28 x 10^19 nm^2 to km^2?
What is the correct option for the conversion of 6.28 x 10^19 nm^2 to km^2?
Final answer: The correct conversion of 6.28 x 10^19 nm^2 to km^2 is 6.28 x 10^11 km^2 (Option 2).
Understanding the Conversion:
To convert from nanometers squared (nm^2) to kilometers squared (km^2), we need to know that 1 km is equal to 1 x 10^9 nm. Therefore, 1 km^2 equals (1 x 10^9)^2 nm^2, which simplifies to 1 x 10^18 nm^2. In this case, we have 6.28 x 10^19 nm^2 to convert into km^2. The conversion involves dividing the value in nm^2 by 1 x 10^18 (the equivalent of 1 km^2 in nm^2). The correct conversion is Option 2: 6.28 x 10^11 km^2. This result is obtained by dividing 6.28 x 10^19 nm^2 by 1 x 10^18. Therefore, Option 2 is the correct answer for the conversion of 6.28 x 10^19 nm^2 to km^2.
