# Converting units: centimeters to meters

Learn how to convert centimeters to meters by understanding the meaning of the "centi" prefix, which represents 1/100. We convert 37 centimeters to meters by dividing by 100, resulting in 0.37 meters. Created by Sal Khan.

- can u also divide by 10?(17 votes)
- Yes, but you will need to divide by ten again because 100 cm equals a meter, and 10 times 10 equals 100.(13 votes)

- How many acres can be fertilized with 1392 gallons of fertilizer?(1 vote)
- This depends on how many gallons of fertilizer you need for each acre. If you need 100 gallons of fertilizer for each acre, then you only have enough for 13 acres, and you'll have 92 gallons of fertilizer leftover. If you need 25 gallons of fertilizer for each acre, then you have enough for 55 acres, and you'll have 17 gallons leftover. If you need 2 gallons of fertilizer for each acre, then you have enough for 696 acres, and you'll have no fertilizer leftover.

Just take 1392, and divide it by the number of gallons you need for each acre.(7 votes)

- no 180 minutes = 3 hours(4 votes)
- you guys are confusing me.(1 vote)

- I have wacthed this like 11 times and i still dont get it(2 votes)
- Just memorize some prefixes and you will be good at converting(0 votes)

- Why bother with having the 0 on the left of the decimal?(1 vote)
- The 0 to the left of the decimal is not absolutely needed, for decimals greater than -1 but less than 1. For example, .042 is the same as 0.042.

However, writing the 0 to the left of the decimal is sometimes preferred style. For example, this 0 is preferred in the type of work that l do (writing mathematics test questions).(4 votes)

- it's kinda confusing/not confusing(2 votes)
- what is difrence between deci and centi(1 vote)
- "deci" means "1/10 of", while "centi" means "1/100 of".

So one decimeter is 10 times as long as one centimeter.(3 votes)

- yes a mile is bigger than a kilo meter(2 votes)
- is it possible to convert from inches to centimeters?(0 votes)
- Yes! One inch is exactly 2.54 centimeters. So we multiply by 2.54 to convert from inches to centimeters, but divide by 2.54 to convert from centimeters to inches.

Have a blessed, wonderful day!(6 votes)

- Useful information that will be used later.(2 votes)

Convert 37
centimeters to meters. Let me write this over. 37, and I'll write centi
in a different color to emphasize the prefix. 37 centimeters, and we want
to convert it to meters. So we really just have
to remind ourselves what the prefix centi means. Centi literally means 1/100th,
or one hundredth of a meter. So this is really saying
37 hundredth meters, so let's write it that way. This is literally
37/100 of a meter. So 1/100 meters. These are equivalent statements. So what are 37/100 of a meter? Well, that's going to be
37/100 of a meter, which can be rewritten
as, if you wanted to write it as a
decimal, that's 0. you could view it as 3/10
and 7/100, or 37/100. So 0.37, 0.37 meters. Another way that you could have
thought about this is look, I'm going to go from
centimeters to meters. I have 100. I need 100 centimeters
to get to one meter, so I'm going to have to
divide by 100 in order to figure out how
many meters I have. And you should always
do a reality check. If I convert
centimeters to meters, should I get a larger
number or a smaller number? Well, however many
centimeters I have, I'm going to have a
fewer number of meters. Meters is a larger unit. So you should have a
smaller value here, and it should be a smaller
value by a factor of 100. So you literally
could have started off with 37 centimeters. Let me write it this
way, 37 centimeters. And actually, let's go
through a couple of the units right over here. Now, if you wanted to turn it
to decimeters, so this is 1/100. Decimeters, one over 1/10. So you would divide. This would be 3.7 decimeters. Let me write this
as 3.7 decimeters. And a decimeter is
1/10 of a meter, so you would divide by 10 again. So this is 0.37 meters. So one way to think about
it is to go from centimeters to meters, you're
going to divide by 100. Dividing by 100, you would
move the decimal space over to the left two times. Doing it once divides by 10. Doing it twice divides by 100. So you get to 0.37 meters.
