Question

How many millimetres are equivalent to $ 8 $ metres ?

Answer 1

Hint: Here this question belongs to the conversion topic that is we have to convert the unit from one form to another. Here we have to convert the unit metres to the unit millimetres. In the question, we have to find what number of millimetres correspond to $ 8 $ metres.

Complete step-by-step answer:
The metres and millimetres are the units to measure the length of physical commodities or items. A metre is abbreviated as m and millimetre is abbreviated as mm. A millimetre is a metric unit of length and it is used for measuring small lengths.
The given question requires us to convert the unit of length. We have to convert $ 8 $ metres into millimetres.
We know that each metre of length consists of $ 1000 $ millimetres. So,
$ 1\;m = 1000\;mm $ .
Let the number of milliliters that correspond to $ 8 $ metres be x.
Then, to convert $ 8 $ metres into millimetres, we follow unitary method where we first find that how many units of milliliters correspond to a single unit of metre and then multiply both sides of the equation by a suitable number so as to get the desired conversion of $ 8 $ metres.
So, $ 1 $ metre = 1000 millimetres
Hence, $ 8 $ metres = 8000 millimetres
Hence, we have converted the metres into millimetres.
So, the correct answer is “8000 millimetres”.

Note: We have different units for solid quantity, liquid quantity and gaseous quantity. Every quantity has a measurement unit from the low quantity to the high quantity. While converting the unit of a quantity from one form to another form we have standard value. By multiplying or dividing we can convert the unit of the quantity. We have a different system of measurement of a quantity.
