American cooks use standard containers, the 8-ounce cup and a tablespoon that takes exactly 16 level fillings to fill that cup level. Measuring by cup makes it very difficult to give weight equivalents, as a cup of densely packed butter will weigh considerably more than a cup of flour. The easiest way therefore to deal with cup measurements in recipes is to take the amount by volume rather than by weight. Thus the equation reads:

1 cup = 240 ml = 8 fl. oz.
