# How do you convert 25.00 mL to qt.?

Feb 4, 2016

Well first, you have to decide what a $\text{QUART}$ is! In the UK this is $\text{2 pints}$, $1200$ $m L$ ($=$ $1.200 \cdot L$). In the States, it is $0.946$ $L$. https://en.wikipedia.org/wiki/Quart

#### Explanation:

In both US and Imperial systems a $\text{quart}$ is short for a QUARTER of a GALLON. Of course, the US gallon and the Imperial gallon are different.

Given that $1$ $U S$ $q u a r t$ $=$ $0.946$ $L$ or $946$ $m L$, $25.00$ $m L$ $=$ (25.00*cancel(mL))/(946*(cancel(mL)*"quart"^-1) $=$ ?? $\text{quarts}$.

It's questions like these that remind me how truly decadent the Imperial system of measurement is: pounds, ounces, feet, furlongs, chains, poles. Of course, we are going to be stuck with these units for some time. In the question above I was able to solve the problem dimensionally, i.e. I had the conversion $m L \cdot {\text{quart}}^{-} 1$, and when I did the calculation the extraneous units cancelled out.

Do not be persuaded that these conversions are easy. Anyone can make an error, and the 2 systems of measurements (actually 3 systems of measurement) are hard to interconvert.
