Question

How do you convert $345cm$ to miles?

Answer 1

Hint: We know that there are different units of lengths , each value has its different value in conversion charts.
As we know when we are converting the value i.e. from Centimetre to miles we have to divide by $16.=0934.4$ here we know $1cm=0.0000062137$ mile.

Complete step-by-step answer:
In the above question we have to convert cm into miles.
The given value in question $345$ cm to miles.
Here we know that Centimetre is actually a unit which is used in day today life to measure the length. But the value is considered metre system. This system actually work on Centimetre gram second system units.
When we are talking about centimetre into index we consider $1cm=0.01$ meter.
Mile is also the unit of distance, it is actually used in the USA and UK where the distance is actually measured in miles.
Thus, when we are talking about conversion.
$1mile=1.609km$
So, we get the value of mile in kilometre. Here we are converting kilometers into meters.
$1mile\cong 1.609km=1.609\times {{10}^{3}}m$
$=1.609\times {{10}^{3}}m\times {{10}^{2}}cm.{{m}^{2}}$
Now, solving we get,
$=1.609\times {{10}^{5}}cm$
Here we are getting into converting mile
$\dfrac{345cm}{1.609\times {{10}^{5}}cm.mil{{e}^{-1}}}=0.0021miles$

Hence when we had converted $345cm$ into miles $0.0021miles.$

Additional Information:
So when we are going to convert the value in another form we have to follow a comparison chart.
The conversion from mile to kilometres
$1$ mile is equal to $1609$ kilometres
$1$ mile is equal to $5280$ feet
$1$ mile is equal to $1760$ yards
Now, converting kilometre into mile
$1$ kilometre is equal to $0.621$miles
$1$ kilometre is equal to $3280.8$ feet
$1$ kilometre is equal to $1093.6$ yards
$1$ kilometre is equal to $1000$ meter

Note:
While when we are considering a conversion we can refer to the conversion chart.
primarily it is observed that when we convert a small unit to a bigger unit we apply division or decimals and when we convert bigger unit to smaller unit we do multiply.
Secondary while converting centimetre to mile we have to multiply centimetre by $0.00000621371.$
which is a conversion factor.
