How do you move the decimal from megameters to meters

How do you move the decimal from megameters to meters?

The Correct Answer and Explanation is:

To move the decimal from megameters (Mm) to meters (m), you need to know the conversion factor between the two units. One megameter (Mm) is equivalent to one million meters (1 Mm = 1,000,000 m).

Here’s how you can convert:

1. Understand the Conversion:
   The metric system follows powers of 10, and each unit is a factor of 10 from the next. So, to convert from megameters (Mm) to meters (m), you multiply by 10610^6106 (which is 1,000,000).
2. Move the Decimal:
   If you have a number in megameters, you move the decimal point 6 places to the right to convert it to meters.
   For example:
   • If you have 3.45 Mm, move the decimal point 6 places to the right:
     3.45 Mm=3,450,000 m3.45 \, \text{Mm} = 3,450,000 \, \text{m}3.45Mm=3,450,000m.
3. Example Calculation:
   • If the distance is 0.007 Mm, moving the decimal point 6 places to the right results in:
     0.007 Mm=7,000 m0.007 \, \text{Mm} = 7,000 \, \text{m}0.007Mm=7,000m.
4. Why the Decimal Moves:
   This is because a megameter is one million meters. So by moving the decimal 6 places, you’re scaling up the value by a factor of one million.

In summary, converting from megameters to meters is a straightforward process of multiplying by 1,000,000 or moving the decimal 6 places to the right. This ensures that the units scale correctly to match the size of the measurement.
