Since length has many English units with different names, some other useful conversion factors for length are:
39.37in = 1m
1 mi = 1.609 km
Another useful conversion factor for mass is:
2.2lb = 1kg
The liter (L) is an established unit of volume in nations using the metric system. It is equal to one cubic
decimeter. (Formerly defined as one kilogram of water.)
surface area
Surface Area of a Cube = 6 a 2
Surface Area of a Rectangular Prism = 2ab + 2bc + 2ac
Surface Area of Any Prism (b is the shape of the ends)Surface Area = Lateral area + Area of two ends(Lateral area) = (perimeter of shape b) * LSurface Area = (perimeter of shape b) * L+ 2*(Area of shape b)
Surface Area of a Sphere = 4 pi r 2
Surface Area of a Cylinder = 2 pi r 2 + 2 pi r h
volume
capacity relation to meter........... amount of space occupied by an object.
mass
roughly weight relation to meter
length
is the distance from one point to another
density
The mass density or density of a material is its mass per unit volume.
