1. Count the Number of Plants per Square Foot
   Measure a one-square-foot section of your rice field and count the total number of plants. Enter this value in the calculator.


2. Determine the Average Number of Grains per Head
   Select multiple sample heads from different plants and count the total number of grains. Calculate the average number of grains per head and enter this value.


3. Measure the Average Grain Weight
   Weigh a sample of rice grains and determine the average weight per grain in grams. A typical value is around 0.02 grams per grain. Enter this value in the calculator.


4. Calculate Rice Yield Estimate
   Click the "Calculate Yield Estimate" button. The tool will compute the estimated pounds per acre using:
   ((Average Grains per Head x Average Weight per Grain x Plants per Sq Ft x 43,560) ÷ (453.6 x 45))
   This formula accounts for plant density, grain production, and standard conversion factors.

For the most accurate results: Sample multiple areas of your field and average the data across different locations.
