hello hejsan hej I am pixelpia
welcome to my channel today I’m going to talk about the differences between the
metric and the imperial system something I struggled with when I first came to
the US if this is your first visit to my channel you are very welcome and if you
are a returning subscriber you are welcome back I would appreciate if you
subscribe to my channel and give it a thumbs up that is if you like it of
course so without further ado let’s get this video started so today I’m gonna compare the metric
system with imperial system something I had trouble with when I first came to
the u.s. most of the world use the metric system but in u.s.we still use the
imperial system I am only gonna talk about mass volume
and length and only go into the most common measurements in the metric system
we use base element for each category and then some prefix to change that
measurement like kilo which is thousand hecto which is 100 deci which is 1/10
centi which is 1/100 and milli which is 1/1000 so the base measurements is meter
for length gram for mass and liter for volume so let’s take a look at the
length the base is 1 meter but if you measure further distances for example
driving distances you use kilometer that is kilo and meter one kilometer is 1000
meter when you measure how high a person is
you measure that in centimeters that is one hundredths of a meter and I am for
example 156 centimeters that’s one meter and a little bit more than a half we use
one measurement that doesn’t follow the system and that is one mil that is
equal to ten kilometers so for length we use kilometer meter decimeter
centimeter and millimeter I will put them up to the screen on this side as you can see we don’t use the comma
for writing 1000 the comma is used as a decimal point between the whole number
and the tenths of a number let’s take a look at mass when we weigh something we
use gram as the base but one gram is a very small quantity so most of the time
we use kilogram that is 1000 gram or if you are baking for example you can use
hectogram it’s 100 grams so I will put the measurements for the grams for
weight up here we have 1 kilogram 1 hectogram
and 1 gram if we are measuring something very tiny for example if you’re
measuring medicine we used milligram that is one thousandth of a gram and
finally let’s take a look at volume the base for volume is liter and we use
liter we use deciliter centiliter and milliliter and I put them all up here now let’s take a look at imperial system
we for length we use mile feet and inches one mile is 5280 feet we also use
yard which is equal to three feet and one foot it was 12 inches for mass we
use pounds and ounces and 1 pound equals 16 ounces for volume we use
gallons quarts pints and fluid ounces one gallon is 4 quarts or 8 pints or 128
fluid ounces so one quart is two pints and one pint is 16 fluid ounces so let’s
compare them in length one meter equals three feet and three and 3/8 inches one
kilogram equals two pounds and 3.3 ounces and finally one liter equals one
point zero five six seven quarts and the other way around one mile is about 1609
meters one yard or three feet is about zero point nine meters one foot is about
zero point three meters and finally one inch is about 2.54 centimeters
one gallon is about 3.78 five liters one quart is about zero point nine five
liters one pint is about 0.47 liters and one fluid ounce is about zero point two
nine five liters but of course I never used that exact numbers when I convert
in my head if you don’t need an exact measurement this is what you can use one
meter is about three feet or one yard one pound is about half a kilogram or
one kilogram is about two pounds one litre is about one quart and a gallon is
about four liters I would also like to talk a little bit about measuring
temperature the two most common scales are Celsius and Fahrenheit in Sweden we
use Celsius and here in the US we use Fahrenheit both scales are based on the
freezing point of water and the boiling point of water if we start with the Celsius
scale water freezes at zero degree Celsius and it boils at 100 degrees for
Fahrenheit the water’s freezing point is at 32 degrees and it boils at 212
degrees if we compare the two scales we can see that one degree Celsius is about
one point eight degrees Fahrenheit but then we have the little problem with
the freezing point being at 32 degrees so there is a little formula to use for
converting from one to the other if I know the degrees in Celsius and want to
find out find the degree in Fahrenheit all I have to do is multiply the degree
in Celsius with one point eight and then add 32 to that answer if I know the
degree in Fahrenheit and I want to find it in Celsius I first subtract the 32
degrees and then I divide the final answer with 1.8 let me give you a couple
of examples up here is it complicated well just as the other measurements I
have simplified it for me when I don’t need an exact measure instead of using
the 1.8 I round that to 2 so if I know that it’s 24 degrees Celsius all I do is
24 times 2 which is 48 and then I add the 32 which gives me 48 plus 32 equals
80 so 24 degrees Celsius is about 80 degrees Fahrenheit
and if I know the Fahrenheit let’s say for example 76 degrees Fahrenheit
and I want to convert that to Celsius I take 76 minus 32 which gives me
44 and I divide that by 2 which gives me twenty two so 76 degrees
Fahrenheit is about 22 degrees Celsius nowadays I seldom do that because I can
easily change from Fahrenheit to Celsius on my phone when I want to know what it
is in one or the other but it’s good to know how to do it quickly in your head
if you want to check what the weather is in the country that use the opposite this is where I’m gonna end today’s
video I hope you enjoyed it next week I’m going to take a look at
Swedish stereotypes and maybe make a little bit fun of myself don’t forget to
subscribe to my channel and if you like this video please give it a thumbs up so
that’s all for today goodbye or as we say it in Swedish
Hej då
