Where the figure comes from
The weight on this page is from the King Arthur Baking ingredient weight chart, which lists corn syrup as 1 cup = 312 g. Scaled to one US cup of 236.59 ml, that is 312 g. Every other number on the page is that figure multiplied or divided.
grams = cups x 312
cups = grams / 312
For example, 1 1/2 cups of corn syrup is 1.5 x 312 = 468 g, and 300 g is 300 / 312 = 0.96 cups.
How corn syrup compares by the cup
A cup measures volume, so its weight depends on what fills it. A cup of corn syrup is 37.4 percent heavier than a cup of water (227 g). It is 160 percent heavier than a cup of all-purpose flour (120 g).

US cup or metric cup
A US cup is 236.59 ml and a metric cup, used in Australia, New Zealand and Canada, is 250 ml. The metric cup is 5.7 percent larger, so it holds 330 g of corn syrup against 312 g. Tablespoons and teaspoons on this page are US spoons. The calculator above has a switch for the cup size.
