Beans Conversion Calculator (Dried, Canned, and Cooked Beans)

This beans calculator provides measurement conversions between cooked vs dried beans. You can toggle between volume (cups, cans) or weight (pounds, ounces, grams). 23 different types of legumes are available for converting. Data is checked against USDA FoodData Central to ensure accuracy and consistency.

27 types of beans and lentils are labelled and pictured in front of a white background.

As you can see from the image above, members of the legume family vary drastically in size. So when you’re converting between volume to weight, or between dried to cooked, there are bound to be differences between different types of beans.

Rules of Thumb

For many bean recipes, it is not necessary to measure out a precise quantity of beans. A chili recipe would likely be just as good whether made with 1 cup of beans, or 3/4 cup, or even 1 ½ cup. The same lentil soup recipe could be made with either 80g, 100g, or 130g of lentils and all you need to adjust is the salt level. For imprecise recipes like these, you can use the following quick-and-dirty rules of thumb for beans conversion:

  • 1 can of beans, drained = 1½ cups cooked beans = 1/2 cup of dried beans
  • 1 lb of dried beans = 2.5 to 3 lbs of cooked beans
  • 1 lb of dried beans = 6 cups of cooked beans
  • 1 15oz can of beans weighs roughly 10oz once drained of excess liquid

However, for some recipes such as black bean brownies or homemade soy milk, it is important to be more accurate when measuring. Particularly when you are scaling a recipe up or down, the effects of using an imprecise conversion ratio will be magnified. That’s when I would use this calculator instead.

How to Use the Beans Conversion Calculator

Simply enter a number into the “Quantity of beans” box, select the type of bean and the measurement you want to convert from, and the program will automatically calculate converted values.

So far, conversions for 23 different varieties of legumes are supported:

  • Adzuki beans (azuki)
  • Black beans
  • Black-eyed peas (cowpea)
  • Black turtle beans
  • Cannellini beans (white kidney bean, fagioli bianchi)

  • Pink beans (chili bean, habichuelas rosadas)
  • Pinto beans (frijoles pintos)
  • Soybeans
  • Split peas (yellow, green)

Notes

  • This calculator uses metric and US imperial measurements. 1 cup = 240mL, 1 oz = 28g.
  • Data is checked against USDA FoodData Central to maintain consistency and accuracy.
  • The beans calculator requires JavaScript enabled in your browser, so if all you’re seeing is a blank screen, use this website to check if JS is enabled.

How to Cook Dried Beans

When cooking from dried, I recommend a 1:4 ratio of beans to water (by volume) for cooking on the stove-top, and a 1:2 ratio for cooking in the Instant Pot.

Example: Cook 1 cup (190g) of chickpeas in 4 cups (960g) of water on the stove, or in 2 cups (480g) of water in the Instant Pot.

Beans Cooking Time

Rule of thumb for cooking most dried beans in the Instant Pot:

  • Unsoaked beans: Use the Beans/Chili function on More mode or the Manual/Pressure Cook function on High Pressure for 40 minutes.
  • Pre-soaked beans: Use the Beans/Chili function on Normal mode or the Manual/Pressure Cook function on High Pressure for 30 minutes.
  • Small beans such as mung beans and adzuki beans can be cooked without soaking using the Beans/Chili function on Less mode or the Manual/Pressure Cook function on High Pressure for 25 minutes.
  • Lentils: Most varieties of lentils are very delicate and become mushy or fall apart under pressure. I recommend using stovetop for cooking lentils.

Up to this point I have mainly cooked beans using the Instant Pot but I am slowly testing out cooking beans using the Dutch oven. I will update this post with stovetop and oven cooking instructions when I finish testing.

Bean Conversion FAQs

What is a 15 oz can of beans equivalent to?

1 15oz can of canned beans is roughly equivalent to 1 ½ cups or 10oz of drained cooked beans, or 1/2 cup of dried uncooked beans. The exact conversion depends on the type of bean, as beans come in different shapes and sizes. Refer to the Beans Conversion Calculator, which allows you to choose between 27 different types of beans, for more precise conversions.

How many cans of beans equal 1 lb dry?

Depending on the type of bean, 1 pound of dry beans is equivalent to 4 to 5 cans of beans. This assumes that the canned beans are in standard 15-oz cans. However, the exact conversion also depends on the brand, as different brands of canned beans may vary slightly in their solids-to-liquids ratio.

How much does 1 cup of beans yield?

1 cup of dried beans yields 2 ½ to 3 ½ cups of cooked beans, which is equivalent to 2 15oz cans.

How do I convert dry beans to canned beans?

A rough rule of thumb you can use is that every 1/2 cup of dried beans equals 1 can of beans. Or use the conversion calculator above for a more precise conversion.

  1. Useful conversion tool, bookmarked. Did you write it yourself? Tonight is turkey chili to use Thanksgiving leftovers, I’m in Louisiana. Needed to convert red kidney beans. 🙂
