# How to convert cm^2 to meter?

I need help to convert cm^2 to meters and vice versa . Please i really need help to calculate pressure which is F/A in which A is area that is supposed to be in m. Correct me if im wrong but 10Newton really is 1kg right?

cm^2 is the unit of Area whereas m is the unit of length. So one can't be converted to the other because they are different quantities.

However cm to m, you divide by 100 e.g 200cm = 2m

cm^2 to m^2, you divide by 100 twice e.g 200cm^2 = 200/100/100=0.02m^2

The standard unit of area is m^2 and not m

10Newton is equivalent to 1kg after multiplying acceleration due to gravity g=10ms^-2 by 1kg

Pressure = Force per unit area = F/A

area has dimensions of m x m = m^2

Also, Force (N) = mass (kg) x acceleration (m/s^2)

So, Pressure (Pascals) = mass (kg) x acceleration (m/s^2) / Area (m^2)..............(1)

So, the units for pressure are Pascals = kg / (m x s^2)

http://en.wikipedia.org/wiki/Unit_conversions

So, you actually need to convert the area in cm^2 into m^2 first. 1m^2 = 10000cm^2

The use a value of 9.8 m/s^2 for the acceleration due to gravity, and include the mass in equation (1) above and you should be able to get the right answer.

No, you need help to convert cm² to m² !

{You are going to get a lot of indignant answers saying "A metre is a measure of length, not area!!!" }

There are 100 cm in a metre.

{You also need to learn about the metric prefixes. There are quite a lot of them. c stands for 'centi' meaning a hundredth. }

Anyway. Imagine a huge sheet of graph paper 100 cm by 100 cm. That's one metre by 1 metre or 1 m² How many centimetre squares does it contain? 100 * 100 = 10000. Yes?

So to convert cm² to m² you need to divide by 10000.

{More outrage on the way :-) 10 N is the gravitational weight force due to a mass of 1 kg. (A better approximation is 9.81 N, but 10 N is considered near enough for 'educational purposes'. }

presuming ur trying to convert cm^2 to m^2

1 cm^2 = 0.0001 m^2

1 m^2 = 10,000 cm^2

cm^2 to m^2 => divide by 10000

m^2 to cm^2 -> multiply by 10000

10,000 cm^2 = 1 m^2

1 kg x 9.81 (acceleration due to gravity) = 9.81 Newtons
