Question

How do you convert $ 25.00mL $ to $ qt. $ ?

Answer 1

Hint: In order to answer this question, to convert the given quantity into the other quantity quarts, we should first know what we mean by quart. Then we should do further conversion.

Complete answer:
In both US and Imperial systems a quart is short for a QUARTER of a GALLON. Of course, the US gallon and the Imperial gallon are different.
Given that- $ 1US\,quart = 0.946L\,or\,946mL,\,25.00mL $
 $ = \dfrac{{25.00.mL}}{{946.(mL.quar{t^{ - 1}})}} = ??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 $ mL \cdot quar{t^{ - 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.

Note:
 The quart was originally a medieval English unit for dry and liquid measures that varied between $ 0.95{\text{ }}and{\text{ }}1.16{\text{ }}litres $ , relatively close to its modern equivalents. In Geoffrey Chaucer ’s Miller’s Tale (about 1370), it was used as a measure for ale.
