The ISO unit of pressure is a Pascal, equal to one Newton per square metre. The best handy representation of a Newton is an apple, so if you liquidize an apple and spread it uniformly over a one metre square manhole cover, the pressure exerted on it is a Pascal. Since this is obviously a totally useless unit of measure, GigaPascals are normally used in engineering calculations. Similarly a Farad approaches the capacitance of the earth, so microFarads are used. The whole metric system is full of these daft units, hence answers to calculations often take the form: answer times ten to some extremely large power. At ;east two space shots are known to have gone wrong because somebody put in the wrong power of ten in the answer.
The imperial system has units for which the values are used only once---for example, 1760 yards to a mile. This number is not used elsewhere and cannot give rise to confusion.
Finally there is not one country in the world that uses the metric system in total as originally proposed---or perhaps you know better? Who uses metric time?
