What do you want to know the weight of, and why?
How do you measure the weight if you are buying bananas--in what units?
What's this silly exception in U.K. metrication laws, now in the 21st century, for continued use of
one of the units in the troy system of weights, the troy ounce, even though Great Britain outlawed
the pound on which those ounces are based back in the 19th century?
If a bar of gold has a weight of 401.23 troy ounces, how much is that in the International
System of Units?
Here's something I don't know the answer to--in what units do most people in the U.K. express their
body weight? What are the second most common units there?
[q1]> Would I have lost the marks if I had been pedantic and really attempted to calculate the weight,[/q1]
[q1]> rather than the mass which is what I think they were looking for?[/q1]
You ought to.
