How to weigh a pumpkin
To compute your pumpkin weight unit , you need to prevail three measurements . If you have a large pumpkin vine , get a mensuration tape longer than 100 inch . If you only have metallic element mensuration tapeline , be certain to get some string to be used as your measure tape . Now , rent ’s get down . Be sure to use the nontextual matter below as a reference .
Measure the circumference of the fruit analog to the ground at fore top . This is measure issue 1 .
Now come in your tape at the works shank to the soil and to the peak end to the ground . What is the aloofness from the ground to the basis ? This is measurement turn 2 .
Now commit your tape perpendicular to the works shank at the broad portion of the Cucurbita pepo . put the tape on the ground on both sides at this broad office . Is it perpendicular to the flora stem ? Now , measure the distance from ground contact to flat coat contact . This is measurement number 3 .
Add all three measuring and find the data in the column inch column below and there is your exercising weight .
entire measurement . This is a rough weight of prescribed point on how to measure
This is the rule
Weight_lbs=(((14.2/(1 + 7.3 * 2^(-(OTT_inches/96)))^3+((OTT_inches)/51 ^ 2.91)-8)*0.993

These mensuration are only for theAtlantic Giant miscellany of pumpkins . These exercising weight estimation chart are intended as a bumpy guide only . This is the best and current method for estimate a Cucurbita pepo ’s weight unit , but will not interchange really librate your pumpkin on a proper set of calibrated scale .
Below is our archive system of weights estimation chart that has been used over the years . Please employ the 2017Giant PumpkinWeight Estimation chart above .
The Circumference Measurement should be taken where you have the LARGEST Circumference . It WILL NOT always be parallel to the ground . It may be above or below the stem and above or below the blossoming stop . On mostlarge pumpkinsthe LARGEST Circumference IS NOT at the stalk / blossom spirit level . The LARGEST Circumference is necessary to obtain the most accurate Weight Estimate as most of the Circumference measurements used to obtain the Weight Equations were the LARGEST Circumference
Updated measuring process and note :
The last update was dated January 2003 based on 800 measurements from 2001 and 2002 . I compared data for 1203 fruit grown in 2003 and 2004 with the 2001 and 2002 data . Fruit grow the last 2 years are heavier for the same size of it by approximately 3 % . Therefore the equation used for the table dated January 2005 are primarily based on 1203 fruit grown in 2003 and 2004 . Most of the data was provide from the AGGC file cabinet by Mike Nepereny . The table provide estimation for fruit down to 41 inch Circumference ( approx . 30 pound ) and 91 inches Over - the - Top ( approx . 21 pound ) .
David Martin from Little Britain , Ontario used Multiple Regression Analysis to obtain equation that comfortably match the data I supply . He make the Weight Tables from those equations .
The OVER - THE - TOP method ( mesa 1 ) provides the BEST estimation but only about 76 % will be within plus or minus 10 % . This requires summate Circumference to the two Over - the - Top measure lead from ground - to - ground from side - to - side and end - to - terminal .
TABLE 2 uses only the CIRCUMFERENCE measurement . It DOES NOT furnish beneficial estimation for outstandingly high , bland , farsighted or short yield . About 54 % of the estimates will be within plus or minus 10 % . It is useful to figure day - to - day increases .
The Circumference mensuration should be theLARGESTcircumference taken more or less parallel to the terra firma . At weigh - offs I have found some growers are not evaluate the largest Circumference which contributes to the variableness . The OVER - TOP measurements from ground - to - soil in both direction must be over the highest head of the fruit . These must be take straight down from the edges of the fruit .
EXAMPLE : Circumference = 175 inch ( board 2 estimate = 1185 pounds)Side - to - side = 103 inchesEnd - to - end = 100 inchesTotal = 378 inches ( mesa 1 estimate = 1130 pounds)The actual weight was 1121 pounds .
Due to considerable variance in the “ wall thickness ” from fruit - to - fruit , neither method provides very authentic estimates but at nowadays , we do n’t have a serious method acting . Here are the pct of your estimate that you could bear to be within the truth ranges show ( ground on fruit farm in 2003 and 2004 ):
NEW Tables compared to January 2003 Tables : The fresh tables should allow for unspoilt estimate as AVERAGE fruit weight for the same measurement increased by some 3 % compare to 2001 and 2002 weight . The Circumference table should be much good at the high weights as the old table over - estimated above approximately 170 - in Circumference .
I will provide David Martin ’s equation ( 4 terms ) to anyone who wants to expend them in a computer program . Write me at 1925 Middle Road , Rush , NY 14543 - 9732 .
I have provided Tables to estimate free weight since 1988 . They were updated every 2 to 3 years . This is my LAST update . For the last 3 updates , I thank David Martin for using the data I provided to prevail the equations and prepare the Tables . give thanks you to all the growers who provided me with measurements since 1987 and to Mike Nepereny for providing data from his AGGC Indian file the last 4 years .
notation : Several people have attempt to receive Weight Estimating equations using the RAW data available . All , that I know of , obtained equations that over - estimated below about 750 hammer and under - estimated above that due to a preconception in the data . If anyone is concerned , I will explain how I wreak around the bias . Leonard B. Stellpflug
