Thousand seed weight formula

The formula for calculating thousand seed weight (1000 seed wt) is:

TSW = (Total weight of seeds in grams) / (Number of seeds counted) * 1000

TSW = thousand seed weight

This formula allows you to determine the weight of a thousand seeds based on sample size.

How to calculate thousand seed weight?

To calculate the thousand seed weight (TSW), you will need a sample of seeds and a balance or scale capable of measuring small weights accurately.

Here’s a step-by-step guide on how to calculate TSW:

  1. Count the total number of seeds in the sample. For accuracy, it’s recommended to count at least 100 seeds
  2. Use a balance or scale to measure the total weight of the seeds in the sample.
  3. Divide the total weight of the seeds by the number of seeds in the sample and multiply by 1000 to obtain the TSW.

Solved Example

Example:- If the total weight of the seeds is 2.2 grams and you counted 230 seeds, then calculate the thousand seed weight.

TSW = (2.2 grams) / (230 seeds) * 1000 = 9.565 grams/1000 seeds

Therefore, the TSW in this case would be approximately 9.565 grams/1000 seeds.
