0.821 qts to ml
The correct answer and explanation is:
To convert 0.821 quarts (qts) to milliliters (ml), you need to use the conversion factor between quarts and milliliters.
1 US quart is equivalent to approximately 946.353 milliliters (ml). Therefore, to convert 0.821 quarts to milliliters, you multiply the number of quarts by the conversion factor: 0.821 qts×946.353 mlqt=776.92 ml0.821 \, \text{qts} \times 946.353 \, \frac{\text{ml}}{\text{qt}} = 776.92 \, \text{ml}
Thus, 0.821 quarts is approximately equal to 776.92 milliliters.
The reasoning behind this conversion involves understanding the relationship between different units of volume. In the case of quarts to milliliters, both are commonly used units of volume, but they belong to different systems of measurement: quarts are used mainly in the United States, while milliliters are part of the metric system. The metric system is based on powers of 10, making it easy to convert between units like liters and milliliters.
The quart is part of the imperial system of measurements, where one quart is equal to 1/4 of a gallon. The US gallon is slightly different from the imperial gallon, so it is essential to use the US gallon conversion when working with quarts in the US system.
When converting between systems like this, using the correct conversion factor ensures accuracy. The factor of 946.353 ml per US quart is precise for most everyday conversions.
