Since you don't know them I'm guessing they're not available in your area so here's a recipe. I haven't tried it myself but it looks right.

What we call corn many places call maize. The cornmeal used for polenta should be a good substitute if that's easier for you to find.

As for measurements:

1 teaspoon= 5 ml.

3 teaspoons = 1 Tablespoon = 15 ml.

2 Tablespoons = 1 (liquid, ergo volume) ounce = 30 ml

2 ounces = ¼ cup = 60 ml

8 ounces = 1 cup = 240 ml

Now, with your scale, you can weigh out 240 ML water, and use that to determine which cup in your cupboard will be most useful. With dry ingredients, don't pack them down, just scoop it in, then scrape to level off the top with the back of a knife.
