Because the metric system is based on steps of 10 while the imperial system is completely random.
For example:
From milimeters to centimeters you multiply by 10.
From meters to kilometers you multiply by 1000
( *10 for decameters, *10 for hectometers, *10 for kilometers: 10*10*10=1000)
From feet to yards you multiply by 3.
From yards to miles you multiply by 1760.
This makes convertering numbers in metric way easier than imperial... you just add or detract zeros.
It's much easier to convert units in the SI system.Don't look now, but the SI system is the "everyday" systemin virtually the whole world outside the USA.
Convert miles to kilometers by multiplying the number of miles by 1.609344, or 1.6 if less accuracy is needed.
You don't have to.Time is measured in the same units in both the Metric and English systems.
English system and SI (metric) have many different units; you have to know what you want to convert, and look up the specific conversion. Quite often, you will want to convert lengths; 1 in. is exactly 2.54 cm. (0.0254 meters); one mile is about 1.6 km.
First, It's called the customary system not the English system. And when the first explorers moved here, their goal was to be different form where they came from, so they invented the customary system!
meteric system
because it is easier to use than the English system. It only uses powers of ten, so it is easier to convert
SI uses base 10, just like our number system, so it is much easier to learn, remember and convert between units.
metric
metric system is based on 10s
cm --> mm is based on the metric system, which is in intervals of 10. This is easier than converting from who knows what from feet --> in. etc. (metric system is easier)
It's much easier to convert units in the SI system.Don't look now, but the SI system is the "everyday" systemin virtually the whole world outside the USA.
Convert miles to kilometers by multiplying the number of miles by 1.609344, or 1.6 if less accuracy is needed.
In the metric system, units relate to one another as multiples of 10. 1000 milimeters/meter x 1000 meters/kilometer = 1000000 milimeters/kilometer In the English system, units non-intuitive, often unwieldy relationships. 12 inches/foot x 5280 feet per mile = something I can't do in my head
