Yogurt in grams, and the sources that only look like two
Plain whole-milk yogurt weighs 245 grams to the US cup. You will also meet 227, and the gap is not a measuring dispute: 227 g is 8 avoirdupois ounces, a rule applied rather than a scale read. Yogurt is where two charts agreeing means less than it looks.
A cup of yogurt, and the eight-ounce rule that missed again
The USDA weighed plain whole-milk yogurt at 245 g a cup. King Arthur prints 227, with no fat or style qualifier on the row, and 227 g is exactly what 8 avoirdupois ounces come to. That rule holds for water and breaks on anything denser, which is the argument the milk master works through in full. Yogurt is denser than water, so it breaks here too. We publish 245 g.
| Authority | A US cup of yogurt |
|---|---|
| King Arthur Baking ingredient weight chart | 227 g |
| USDA FoodData Central | 245 g |
Yogurt conversions in full
Every row follows the USDA's 245 gram cup. A whole cup of yogurt in grams is the usual lookup, and the fractions come off the same measurement.
| Plain yogurt | Grams | Ounces |
|---|---|---|
| 1/4 cup | 61.3 g | 2.2 oz |
| 1/3 cup | 81.7 g | 2.9 oz |
| 1/2 cup | 123 g | 4.3 oz |
| 3/4 cup | 184 g | 6.5 oz |
| 1 cup | 245 g | 8.6 oz |
| 2 cups | 490 g | 17.3 oz |
Density used: 1.04 g per ml, heavier than water at 1.00.
Two Japanese tables that are one table
Benricho and Kyoritsu both weigh a 200 millilitre cup of yogurt at 210 g. Two independent tables landing on the same figure would be strong evidence. These are not independent: Benricho footnotes the row as taken from Kyoritsu, so what looks like agreement is one measurement printed twice. On butter the same pair diverge, 12 g against 13 on the spoon, and that disagreement is worth more than this agreement. Before counting two sources as corroboration, check whether the second one went to the kitchen or to the first one's table. Working out which figures are independent is most of what the methodology page does.
Thirty grams apart in Australia
Sanitarium weighs a 250 millilitre cup of yogurt at 250 g and Australian Women's Weekly at 280: 30 grams between two charts in neighbouring aisles. We take Sanitarium's 250, which sits nearer the US figure once the cup sizes are allowed for. Neither chart states how it filled the cup, so the 30 grams stay unexplained here rather than guessed at.
| Cup | Plain yogurt |
|---|---|
| US customary | 245 g |
| Metric (250 ml) | 250 to 280 g |
| Japanese (200 ml) | 210 g |
Questions about yogurt weight
- How many grams is a cup of yogurt?
- 245 g for plain whole-milk yogurt, from the USDA. King Arthur prints 227, which is 8 avoirdupois ounces rather than a weighing, the same shortcut that misprices a cup of milk.
- Is Greek yogurt the same weight?
- We do not publish a Greek figure, because no authority we hold weighs one. Strained yogurt has had whey removed and is thicker, so treating it as plain yogurt is a guess. A tub with grams on the label beats any chart here.
- Why do two Japanese tables both say 210 grams?
- Because they are one table. Benricho carries 210 g for a 200 ml cup and footnotes the row as taken from Kyoritsu, so the agreement is a reprint, not a second measurement.
