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.
