To convert milliliters (mL) to liters (L), we use the conversion factor that 1 liter is equal to 1000 milliliters. Therefore, to convert 707 mL to liters, we divide 707 by 1000.
Step 1: Conversion Factor
To convert from milliliters (mL) to liters (L), we use the conversion factor:
\[
1 \, \text{L} = 1000 \, \text{mL}
\]
Step 2: Calculation
We need to convert \( 707 \, \text{mL} \) to liters using the formula:
\[
\text{liters} = \frac{\text{milliliters}}{1000}
\]
Substituting the value:
\[
\text{liters} = \frac{707}{1000} = 0.707
\]
Final Answer
The conversion of \( 707 \, \text{mL} \) to liters is:
\[
\boxed{0.707 \, \text{L}}
\]
