Enter the total weight (grams) and the total number of seeds into the Thousand Seed Weight Calculator. The calculator will evaluate the Thousand Seed Weight. 

Thousand Seed Weight Formula

The following two example problems outline the steps and information needed to calculate the Thousand Seed Weight.

TSW = W / #S * 1000

Variables:

  • TSW is the Thousand Seed Weight (grams per 1000 seeds)
  • W is the total weight (grams) 
  • #S is the total number of seeds 

How to Calculate Thousand Seed Weight?

The following steps outline how to calculate the Thousand Seed Weight.

Example Problem #1:

  1. First, determine the total weight (grams). 
    • The total weight (grams) is given as:: 400.
  2. Next, determine the total number of seeds. 
    • The total number of seeds is provided as: 500.
  3. Finally, calculate the Thousand Seed Weight using the equation above: 

TSW = W / #S * 1000

The values provided above are inserted into the equation below and computed.

TSW = 400 / 500 * 1000 = 800 (grams per 1000 seeds)


Example Problem #2: 

For this problem, the variables required are provided below:

total weight (grams) = 200

total number of seeds = 2000
