You can't convert them, because cm^2 is an area, and liter is a volume.
1 liter = 1000 cm cubed.
1144cm3 would be 1144/1000 =1.144Liter
but 1144cm2 can't be converted to liters
cm2 = area units.
Liters=volume units.
you can't.
cm2 is a measure of area, Liters are a measure of volume, as is cm3.
You can't convert area to volume without additional information.
One cubic centimeter = one thousandth of a liter
1000 cubic centimeters = one liter
1144 cubic centimeters = 1.144 liter
1144 square centimeters = 0.1144 square meters
To convert 1144cm3 {note, it's cubed}, move the decimal place over 3 places, hence 1.144L
1144cm3 you mean... It's1.144 liter
