Measuring Confusion

This is for all of us that are confused with measuring. ( like i was a
while back)
after looking over some of the old posts and researching on Duncans web
page i came up with the following.  best of luck to all.

There are two common ways of estimating your pumpkins weight:
1)  the Circumference method
2)  the Over The Top method

CIRCUMFERENCE METHOD
The circumference measurement is obtained by taking one measurement on
the pumpkin.  Not nearly as accurate as over the top but good for quick
day to day gain.
 	The Circumference measurement (c) or (circ) is the largest
circumference taken parallel to the ground at approximately the
stem-blossom level.  Start at the stem go around the blossem end then
back to the stem on the other side, stay parallel to the ground the
whole way around.  (Circumference is not measured under the pumpkin from
side to side,  which is what I thought for a while.)

Take this number and raise it to the 2.61374 power then times by
0.001517.  This is the estimated weight of the pumpkin. 
For example:
		a 39 inch (c)  pumpkin would be 21.8 lbs
    	a 146 inch (circ) pumpkin would be 688.7 lbs

For those who don't like the math here is a table,  look for your
circumference measurement number in the inches column and next to it is
the estimated weight.

OVER THE TOP METHOD
Over the top (OTT) measurement is obtained by adding the following three
measurements:
1) 	Circumference
2) 	Over the Top front to back
3) 	Over the Top side to side

1) The Circumference measurement (c) or (circ) is the largest
circumference taken parallel to the ground at approximately the
stem-blossom level.  Start at the stem go around the blossem end then
back to the stem on the other side, stay parallel to the ground the
whole way around. (same as in the other method)
2) The Over-Top front to back measurement (fb) is from ground-to-ground
over the highest point of the fruit, from steam end to blossom end.
Measure from the ground below the stem up over the pumpkin past where
the blossom was to the ground. The measurement must be taken straight
down from the edges of the fruit. DO NOT follow the contour of the fruit
to the ground.
3) The Over-Top side to side measurement (ss) is taken perpendicular to
the Over-Top front to back measurement, Measure from the ground on one
side up over the highest point of the fruit and down to the ground on
the other side.  Again the measurement must be taken straight down from
the edges of the fruit. DO NOT follow the contour of the fruit to the
ground.

Many grower just give the three numbers like 99/58/55, or 99(c) 58(fb)
55(ss).

Add all three measurements to get the OTT.  Then raise the OTT to the
2.76 power and then times by 0.0000795. 

For example a pumpkin with circumference of 99 inches and a front to
back of 58 inches and a side to side of 55 inches would have an over the
top or OTT of 212 and the estimated weight would be 209 pounds. A 350
inch  pumpkin would be 835.6 lbs. 

Again for those who don't like the math.  Find the OTT number in the
inches column and next to it is the estimated weight.

or you can enter the OTT number in to Duncans program and it will give
you the estimated weight.
