0.9 L = __ mL
The Correct Answer and Explanation is:
Answer:
0.9 L = 900 mL
Explanation
To convert liters (L) to milliliters (mL), we need to understand the relationship between these two units of volume. Both liters and milliliters are part of the metric system, which is based on powers of ten. This makes conversions between units straightforward once you know the conversion factor.
One liter is equal to 1,000 milliliters. This means that every liter contains one thousand milliliters. The conversion factor you use to go from liters to milliliters is therefore 1,000.
To convert 0.9 liters to milliliters, you multiply the number of liters by the conversion factor:
0.9 L × 1,000 = 900 mL
This calculation shows that 0.9 liters is equal to 900 milliliters. The decimal 0.9 represents nine-tenths of a liter. Since 1,000 milliliters make up one liter, nine-tenths of that would be:
(9 ÷ 10) × 1,000 = 900 mL
Another way to look at it is to move the decimal point three places to the right when converting from liters to milliliters. This is because multiplying by 1,000 adds three zeros to the number. So:
0.9 → 9.0 → 90.0 → 900.0 → 900 mL
This is helpful when converting without a calculator. Knowing that metric units follow a decimal-based system makes conversions like this very efficient and reliable.
Understanding these conversions is useful in many real-life situations. For example, when reading the volume of a liquid medicine, a drink, or even when following a recipe, you may need to switch between liters and milliliters. This is especially important in science, cooking, and healthcare, where precise measurements matter.
So, 0.9 liters equals 900 milliliters.
