Peanut M&Ms in a Jar

The Peanut M&Ms in a Jar calculator computes the approximate number of Peanut M&M sized candies that can be found in a cylindrical jar.

INSTRUCTIONS: Choose units and enter the following:

• (d) Inner Diameter of Jar
• (h) Height of Candy in Jar
• Choose the type of candy.  Jelly Beans are the default candy, but the user can choose Mini Jelly Beans, Regular Jelly Beans, Jumbo sized Jelly Beans, M&Ms, Peanut M&Ms or Gum Balls.

Peanut M&M's in a Jar (JB): The calculator returns a very good estimate of the number of candies in the container. This is useful to guess how many jellybeans are in a jar.

The Math

People are not good a making estimates of the number of small objects in a volume, such as in this example.  This calculator goes about it scientifically.  First, the input parameters are used to compute the volume of the container holding the candies.   This is a straigh forward computation of the Volume of a Cylinder (CLICK HERE).  Then the volume is divided by the number of candies that fit into a standard size volume.  To get these numbers, a large number of the different kinds of candies were emptied into a half gallon measuring cup.  Then they were counted to see how many Jelly Bellys, regular jellybeans, jumbo jellybeans, M&Ms, Peanut M&Ms and finally gumballs fit in the half gallon container.  From there, it's just math.
