Answer for screen readers
The final answer is ( 0.045 ) m.
Steps to Solve
- Identify the conversion factor
To convert millimeters to meters, we need to know how many millimeters are in a meter. There are 1000 millimeters in 1 meter.
- Set up the conversion
We will use the conversion factor to set up our calculation. The formula can be expressed as follows:
$$ \text{meters} = \text{millimeters} \times \frac{1 \text{ meter}}{1000 \text{ millimeters}} $$
- Perform the calculation
Now, substitute 45 millimeters into the formula:
$$ \text{meters} = 45 \text{ mm} \times \frac{1 \text{ m}}{1000 \text{ mm}} $$
- Simplify the result
Calculating the above gives:
$$ \text{meters} = \frac{45}{1000} \text{ m} = 0.045 \text{ m} $$
The final answer is ( 0.045 ) m.
More Information
This conversion shows how to move between different units of measurement. Millimeters are often used for small lengths, while meters are the standard unit for longer lengths in the metric system. Understanding these conversions is essential for precise measurements in scientific and everyday applications.
Tips
- A common mistake is forgetting the conversion factor and using an incorrect value, such as confusing the number of millimeters in a centimeter (which is 10) instead of meters.
- Another mistake is misplacing the decimal point in the final answer.
