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:

- First, determine the total weight (grams).
- The total weight (grams) is given as:: 400.

- Next, determine the total number of seeds.
- The total number of seeds is provided as: 500.

- 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
