Any accurate gram scale. The key is that it is repeatable meaning that you place an object onto its platform numerous times and each time it shows the same weight.

Les Andrews book says Pistons 476.8 grams but different manufacturers have different weights. I had two pistons in my car that differed by 100 grams

Connecting rods 623.7 grams Balance weight 552 grams +- 1 gram crank end, 198 grams +- 1 gram pin end

Should be done on a balance-scale for best accuracy, and big-end and small-end separately as ahirt says. Having said that, the Post Office sells an electronic scale that will read in ounces or grams, and is quite accurate and reasonably priced.

There are different brands of scales but this is essentially what rod weighing looks like.
