Spices, Mustard Seed, Ground: mL to Grams Conversion
Ground mustard seed is a fine, dry powder with a remarkably low density of 0.406 g/ml, meaning one US cup weighs only about 96 grams and a tablespoon just 6 grams. Because the milled seeds trap a large amount of air between particles, ground mustard occupies far more volume per gram than liquid condiments, and it is used in dry rubs, homemade mustard preparations, salad dressings, and spice blends for its sharp, pungent heat.

How this conversion works
Milliliters measure volume while grams measure weight. Because Spices, Mustard Seed, Ground has a density of 0.406 g/mL, 10 mL weighs 4 g — not 10 g as it would for water. This converter uses the real density of Spices, Mustard Seed, Ground so every measurement is accurate.
Measurement notes
Values are rounded to the nearest whole gram. Actual weight can vary slightly with compaction, temperature, and brand. For precision baking, a kitchen scale is always more reliable than volume measurements.
FAQ
- Why is ground mustard powder so light per cup compared to liquid mustard?
- At only 0.406 g/ml, ground mustard seed is a dry powder full of air gaps between particles, so a cup weighs just 96 grams, while prepared liquid mustard is over twice as dense because the powder has been hydrated and compacted.
- How much does a tablespoon of ground mustard seed weigh?
- One tablespoon (about 14.8 ml) of ground mustard weighs approximately 6 grams at 0.406 g/ml, which is less than half the weight of a tablespoon of water and reflects the airy nature of finely milled dry spices.
- Should I measure ground mustard by weight or volume for accuracy?
- Weight is far more reliable because ground mustard's 0.406 g/ml density varies significantly with how tightly the powder is packed or sifted, and a loosely scooped cup can weigh noticeably less than a firmly tapped one.
