Counting by weighing is an approximate procedure for obtaining a given number of items based on an estimate of how much the items will weigh. The procedure can be considerably faster than exact counting. We show how the effects of counting by weighing can be assessed, using a particular problem in seed testing for illustration. We find that using counting by weighing in place of exact counting has little effect on the outcome of the seed test provided that the coefficient of variation of the individual seed weights is not too large, and provided a sufficiently large initial sample is used to estimate mean seed weight.
