Although numerous things such as emotion and thought may be difficult to measure, some things are much easier to quantitize. Measurement changeer aids in changeing one measurement to another similar measurement. Why people care so much about measurements and conversions still remain a mystery to one such as myself. I am convinced however that there could be a useful purpose for it. A recipe for example might be written in the metric system. Someone,havingonlycups,tablespoons, teaspoons and the like could find it distressing when attempting to follow such a recipe. Using a tool such as Measurement changeer would, in this unique particular situation, prove useful. On the other hand, there are numerous situations where a tool such as Measurement changeer would not provide much support. Cooking over an open fire while camping could be a possible example where a tool such as Measurement changeer would not be very useful. Every time I went camping as a boy scout I was instructed to locate a current bush which would supposedly allow us to plug in any electrical device we may have brought. To this day I have not found one yet. Seeing that a tool such as Measurement changeer generally runs on a computer - and a computer of course requires electricity, I believe a too such as Measurement changeer would not be very useful when cooking over an open fire while camping. This does not mean that a tool such as Measurement changeer is entirely useless. Inquiring minds often pose questions that can only be answered by changeing one measurement to another. I once heard of a rocket that did not make it into orbit simply because the programmers forgot to change feet to meters. Of course that is just hearsay. If it were true, however unlikely, then I would be inclined to reason that a tool such as Measurement changeer may have proved quite useful. It appears to me however, that whoever made such an error did it out of absent mindedness - and not out of ignorance.
