Eighth vs quarter: what comes after an eighth?

A quarter comes after an eighth: 7 grams against 3.5. Here is how the two compare, side by side, with a converter to check any weight.

A quarter comes after an eighth. An eighth is 3.5 grams, an eighth of an ounce. A quarter is 7 grams, a quarter of an ounce — exactly two eighths. After the quarter comes the half (14 grams), then the ounce (28 grams). The whole ladder doubles at every step.

The ladder, smallest to largest

• 1 gram — the smallest size most shops sell.
• An eighth, 3.5 g — one eighth of an ounce.
• A quarter, 7 g — two eighths.
• A half, 14 g — four eighths, two quarters.
• An ounce, 28 g — eight eighths, four quarters.

Why the names are fractions

Flower has always been sold in fractions of an ounce, not in metric steps, so the names stuck even after scales went digital. “An eighth” and “3.5 grams” are the same amount said two ways; the trade rounds an ounce to 28 grams (strictly 28.35), which is why the eighth is 3.5 and not 3.54.

Does a quarter look twice as big?

Not always. Weight and volume are different things: a light, airy strain takes up far more room than a dense one at the same weight. A quarter of fluffy flower can look like much more than two eighths of something tight and heavy, and both read 7.00 on the scale. If you want to see it, ask a budtender to set the sizes side by side.

Every size here is well inside New York’s three-ounce limit for adults 21 and over. For the full chart and the scale game, see the weed measurements guide.
