all right so today i thought i'm gonna make a video about converting fahrenheit to celsius and
the other way around pretty much it's 80 fahrenheit today it's hard to believe that
about a week ago it was 15 fahrenheit freezing and snow
so you can see here a lot of the plants
see this was all green
ten days ago in chicago even zero during the day
is pretty much normal but here 15 during night or 10 during night it's like catastrophic
for some of these plants
so just to show you the type of damage here to the trees
like this thing right over here used to be green 10 days ago now i don't know
if the camera is gonna pick it up but you can see how this is all yellow and stuff
so we're gonna do the conversion in a couple of ways we'll use
a function that will be very easy to do the conversion and that's gonna show you how to do the
conversion actually between all kinds of different units uh not just fahrenheit and celsius example
but then we'll also just dive right in and do some examples of using
actual you know formulas how the actual math works behind it so generally when i try to do
this in my head i'll just take whatever number it is so let's say it says like 80 fahrenheit right
i'll just take 80 minus 30 so it will get me to 50 then divided by two and that gives me
about what i need it to be but we're gonna do a little better conversion
so let's just get to our spreadsheet all right let's just do a conversion here so let's say we
have 80 here we now want to convert that so all we have to do with a function just do equals and use
the function convert and basically the first thing is going to be the value so i'm going
to just click on this comma and then the unit we're converting from so that's going to be f
for fahrenheit in quotes and then after comma what i'm converting that to so we'll use
c and there we go that's our conversion just like that we could also do it the other way around
so you can probably guess what that's gonna be like so we're gonna take this click on that
comma and then we're gonna start from c comma and we're gonna convert it to f just like that
and that's the conversion and as you can imagine we can do this with many different units here
see it's giving us this example
but let's just go and see what other units we have so i'm gonna do learn more scroll down
and see right here we have examples of a bunch of different units that we can convert from or to
as you can see many options here so if we wanted to take miles for example here and
convert it to meters we can do that so we can just close this
and let's say we have two miles so we can convert that click on that and this is gonna be from mi
and we're gonna convert it to meters right in here
so there you go so if you wanted that to be kilometers you can just divide us by
a thousand and there we go so if we change it to one see that's our conversion just like that
so now let's do the math behind this fahrenheit to celsius so if i open this wikipedia article
let's scroll down let's see what a formula is really quickly so there you go so what
we're going to do here we're going to take the fahrenheit minus 32 and multiply it by this
so let's do that so i'm going to go here take this minus 32
and whatever we get we need to multiply that
by this so if we hit enter see we got the same answer here so that's the actual formula here
we do minus 32 and multiply it by this
and we get our number or we can do the other way around so this is the way we did it here so we're
gonna basically reverse this so to reverse that we have to basically see here we'll multiply by this
now we can divide by that and then do plus this so we'll go here take our number and divide it by
that and add 32. and that should give us the 80 we're looking for
we can also instead of dividing by this we can just reverse this and multiply it
by that so that should give us the same 80 which is our fahrenheit number
now we can also get rid of these parentheses and it should still just work so that's
the conversion the other way around if we want to do this so let's just check what 15 fahrenheits
would be so that would be like negative 10 or something like that so 10 is like negative 12
so there we have it thanks for watching please subscribe and i'll see in the next video
