Question from Claudette, a parent: Costco sells bags of dirt in the quantity "55 quarts".. This makes no sense to me. Thanks! |
Hi Claudette.
Life would be so much simpler if we all used metric, but we don't. From what I can tell, there is only one definition of a cubic yard, but at least five definitions of what a quart is.
According to www.onlineconversion.com, the equivalences in
alphabetical order are:
55 quart [Germany] = 0.082 371 067 cubic yard
55 quart [ancient hebrew] = 0.077 692 266 cubic yard
55 quart [UK] = 0.081 758 342 cubic yard
55 quart [US, dry] = 0.079 218 844 cubic yard
55 quart [US, liquid] = 0.068 078 061 cubic yard
Compare this to converting between cubic meters and liters in metric:
1000 liters = 1 cubic meter.
