How can I weigh dry ounces without a scale?

[boralyl]

So I need to make a starter (first time with liquid yeast) so I can brew in a few days with plenty of healthy yeast. I used mrmalty.com(SG 1.052) calculator to determine the size of my starter (1.04L). To make this I calculated I need 3 ounces of DME. Unfortunately I do not have a scale. What would be the best way to weigh this out or guesstimate it?

Thanks in advance.

I'd figure 1/3 cup = 2.6 ounces so hey grab a 1/3 cup measure heaping a bit not just level, and rock with it, I can't imagine an extra or a missing half ounce is gonna make or break it. But I'm very unscientific like that So you might not want to listen to me.

grimster's advice will work until you get a scale.

oh, and get a scale!

1 cup per quart works nice... no idea of gravity.
