How much fresh jalapenos equal can?

Typically, one medium-sized fresh jalapeño pepper equals about 1 to 2 tablespoons of diced peppers. A standard can of diced jalapeños usually contains about 4 ounces, which is roughly equivalent to 4 to 6 fresh jalapeños, depending on their size. For recipes, it's best to adjust based on personal heat preference, as fresh jalapeños can vary in spiciness.
