Unsure how many jalapenos you need to buy for your recipes? This article will give you an idea!
One jalapeno with seeds weighs around 0.5–1 oz (15–25 g). A cup of sliced fresh or canned jalapenos has a similar weight, based on our conversion below.
Jalapenos are harder to measure than liquids or granules, but estimates are still a helpful guide. Find out the conversions below!
Sliced Jalapeno Conversions
Sliced jalapenos are usually sold in cans or in jars, but can also be purchased fresh. Whole jalapenos are available fresh, canned, or in jars.
Jalapeno peppers are pretty small compared to other chili peppers. That’s why, when canned or jarred, they are available whole or sliced into halves, thirds, quarters, nacho-sliced, or in the smallest size, diced.
One whole jalapeno pepper with seeds weighs approximately 0.5–1 oz (15–25 g). One cup of sliced jalapeno pepper without seeds weighs around 3 oz (90 g) (source: Cook’s Info). Are you curious about whether it’s safe to eat jalapeno seeds and what could happen if you do? Consider referring to my guide as a valuable resource on this topic.
Half a cup of fresh jalapenos (in slices) weighs 1.59 oz (45 g,) which is around the same number as canned seedless jalapenos, whether whole or sliced (source: Healthy Moms).
The following tables will show you their estimated conversion in cups, ounces, pounds, and gallons using the conversion above, particularly the biggest number.

Diced or Minced Jalapeno Conversions
According to the above conversion where one jalapeno pepper weighs about 15–25 g, one tablespoon would be 1–2 jalapeno peppers.
A can of Ortega Diced Jalapeno Peppers, for example, has a net weight of 4 oz. If we compute the whole 4 ounces, based on the conversion above, that would mean the can has 2–4 peppers.
Since the conversion between fresh and sliced are similar, this would mean they are approximately the same.
Remember that these computations are estimates and approximate. No exact standard conversion for vegetables has been established by authorities.
Moreover, other factors can affect the overall weight of jalapenos. The weight of fresh jalapenos can be affected by their stems and seeds inside. On the other hand, the weight of canned jalapeno peppers will be affected by the brine.
