I'll give you an example i'm 70 inches tall if i do 70 / 12 = 5.83ft
OpenStudy (mindblast3r):
that .83 doesn't mean i'm 5 ft 8..
hartnn (hartnn):
you want to convert your answer to inches^2 ?
OpenStudy (mindblast3r):

hartnn (hartnn):
then 14ft^2 is correct, why even bring inches into picture ?
OpenStudy (anonymous):
No it's already in feet, just leave it as it is.
OpenStudy (mindblast3r):
wait let me upload something
OpenStudy (mindblast3r):
OpenStudy (mindblast3r):

OpenStudy (mindblast3r):
or do 3/12 and turn it into 11.25?
OpenStudy (mindblast3r):
the .3
hartnn (hartnn):
no
that " means inches
so you need to convert it into fee
hartnn (hartnn):
*feets
OpenStudy (anonymous):

OpenStudy (anonymous):
err 90" and 30"
OpenStudy (mindblast3r):
lol i'm talking about the 11' 3".
hartnn (hartnn):
11' 3" means 11 foot 3 inches
OpenStudy (anonymous):
11'3" = 11.25 feet
OpenStudy (mindblast3r):
yah, so how i would write it like 11.3?

hartnn (hartnn):
so, ti bring everything in one units
you need to convert that 3 inches to foot
finally 11.25 foot is correct
OpenStudy (mindblast3r):
ah... so i would have to convert the 3.5 (the .5 part to ft)
OpenStudy (anonymous):
If that's what you meant, yes :)
OpenStudy (mindblast3r):
|dw:1399599618261:dw|
hartnn (hartnn):
no
is it 3.5 ft o
or
3' 5"
?

OpenStudy (anonymous):
If it's 3.5ft you leave it, because it's already in feet lol
OpenStudy (anonymous):
hahaaaa
hartnn (hartnn):
3.5 ft is already in foot
no need to convert anything
3'5" is not in foot
OpenStudy (anonymous):
I think you're overthinking this Mindblast3r.
OpenStudy (mindblast3r):
ahh.. yeah @batman i was thinking the same thing lol. but um

wait so like i got 3.5 by 42 / 12 = 3.5ft
OpenStudy (mindblast3r):
does this mean i convert .5 into ft? or it's already foot?
OpenStudy (anonymous):
42 inches = 3.5 ft yes
OpenStudy (anonymous):
It's already in ft lol
OpenStudy (anonymous):
Look at the units, if it was in inches, it would say 3'6"

hartnn (hartnn):
if you see a sign "
or if it is explicitly written "inches"
only then its in inches
else its in foot
OpenStudy (anonymous):
But in your question it's strictly ft.
OpenStudy (mindblast3r):
but like.. i'm 70 inches tall for example if i do 70 / 12 = 5.83
OpenStudy (mindblast3r):
70 inches is 5'10"
OpenStudy (mindblast3r):
but it shows 70 / 12 = 5.83

OpenStudy (anonymous):
you're 5.83 ft
OpenStudy (mindblast3r):
if you do .83 x 12 = 9.96
OpenStudy (anonymous):
and you're also 5 feet 10 inches :)
hartnn (hartnn):
thats because you have explicitly written 70 "INCHES"
thats why 70 is in inches and u need to convert it to ft
OpenStudy (mindblast3r):
yah. i did 70 divided by 12 = 5.83

That's because you're strictly converting inches to ft there.
OpenStudy (mindblast3r):
.83 is?? 83% of a ft?
OpenStudy (anonymous):
.83 is ft
