Starting from a glossary shop to geometry every where we required units of weights & measures. Without these knowledge any one can cheat us easily. Before paying money we need to know what every the quantity we are purchasing that is accurate. To measure quantity units are the key. In this session I am with all kind of day-to-day use Units of Measurement and Metric Conversion Table. You can use this cheat sheet to learn units of various measurements. In below I have units for length, Area or Surface, Volume, Capacity, Mass & Geometric formulas. These information can also be used for physics to mathematics.

Geometric Formulas
b = base; C = circumference; d = diameter; h = height; l = length; r = radius; w = width; pi = 3.1416
Circle
Area = pi x r square
Area of Sector = 1/2r x length of arc
Circumference = pi x d or 2 x pi x r
Diameter = C / pi
Radius = C / 2 x pi
Cone
Volume = 1/3 h x (area of the base)
Cylinder or Prism
Volume = h x (area of the base)
Cube or Rectangular Box
Volume = 1 x w x h
Cylinder
Area = 1 x w
Triangle
Area = 1/2 b x h
Sphere
Surface Area = C x d
Volume = 1/6 (surface area) x d
Circumference = 3.8978 x qube root of volume
Diameter = 1.2407 x qube root of volume
Diameter = .56419 x square root of surface
