6.3E10 Mm converted to mm would be?

Round the following measurment to three significant figure: 0.90985 cm^2

Is that 6.3E10 megameters to mm.

Mega = 1E6
kilo = 1E3
m = 1E0
mm = 1E-3
So Mega to milli is 1E9 so move decimal point to the right 9 places
6.3E10 x 1E9 = 6.3E19 mm

0.910 cm^2

To convert 6.3E10 Mm (megameters) to mm (millimeters), we need to understand the relationship between these units.

1 Mm is equal to 1 million millimeters, or 1 x 10^6 mm.

So, to convert from Mm to mm, we multiply the value by 1 x 10^6:

6.3E10 Mm * 1 x 10^6 mm/Mm = 6.3E10 x 1 x 10^6 mm

Now, we can simplify the calculation:

6.3E10 x 1 x 10^6 = 6.3E16 mm

Therefore, 6.3E10 Mm is equal to 6.3E16 mm.

Now, let's move on to rounding the measurement 0.90985 cm^2 to three significant figures.

Significant figures are digits that carry meaning contributing to the precision or accuracy of a number. To round a measurement to three significant figures, we follow these rules:

1. If the digit to the right of the third significant figure is less than 5, we simply drop all the digits to the right.

0.90985 cm^2 --> 0.909 cm^2

2. If the digit to the right of the third significant figure is 5 or greater, we increase the third significant figure by 1.

Therefore, the rounded measurement of 0.90985 cm^2 to three significant figures is 0.909 cm^2.
