There are lots of recipes out there that call for 1/4 teaspoon of some kind of spice. That's easy to measure if you have the typical 1/4tsp, 1/2tsp, 1tsp, and 1TBS set. Not so easy on a low-cost kitchen scale (that still costs more than the spoon set!) that can't measure 0.6 grams accurately. So you need to get specialized equipment anyway.
good point. i haven't seen such recipes yet, but i checked my scale and found that, while it claims to have 0.1g accuracy, it doesn't do well with amounts less than 0.5g.
(it's rather wierd. it does go up in 0.1g steps after 0.3g, but if i add something heavier and reset to 0, i have to add more than 0.3g again before it shows a change.)
