You've found a Swedish recipe that calls for "2 kkp of flour," and now you're staring at your measuring jug wondering what on earth a kaffekopp is. Or maybe you're scaling a Nordic bakery's production run and need everything in metric units your equipment understands. Either way, you're in the right place. This guide breaks down the kaffekopp-to-cubic-decimeter conversion in plain language, so you can get back to cooking, baking, or calculating without the guesswork.
What Is a Kaffekopp?
A kaffekopp (plural: kaffekoppar) is a traditional Swedish unit of volume. The name literally means "coffee cup," because the unit was originally based on the amount of liquid a typical Swedish coffee cup holds. It's abbreviated as kkp, which you'll often see in Scandinavian cookbooks and recipe websites.
In modern Swedish kitchen practice, one kaffekopp is standardized at 150 milliliters. That makes it a handy mid-sized measure: larger than a deciliter (100 ml), smaller than a glass (200 ml), and sitting comfortably between a teaspoon-based system and full liters.
Kaffekoppar appear most often in recipes for baked goods, sauces, batters, and drinks. If you've ever browsed recipes from Sweden, Norway, or Finland, chances are you've seen quantities listed in kkp alongside msk (matsked, tablespoon) and tsk (tesked, teaspoon).
What Is a Cubic Decimeter?
A cubic decimeter, abbreviated dm³, is the volume of a cube measuring 10 centimeters on each side. Picture a box the size of a small milk carton base, ten centimeters wide, deep, and tall.
Here's the part that makes life easy: one cubic decimeter is exactly one liter. This isn't an approximation or a rounding convention. It's a direct equivalence, which means any calculation involving dm³ can be read as liters and vice versa.
Because it belongs to the metric system, the cubic decimeter scales cleanly with other units. One dm³ equals 1,000 cubic centimeters (cm³) and 1,000 milliliters. That tidy structure is why scientists, engineers, and international food producers prefer metric volumes over cup-based systems.
The Relationship Between Kaffekopp and Cubic Decimeter
Both units measure volume, so converting between them is straightforward once you know the bridge between them:
- 1 kkp = 150 ml = 0.15 dm³
- 1 dm³ = 1,000 ml ≈ 6.67 kkp
Converting Kaffekopp to Cubic Decimeter
To convert kkp to dm³, multiply the number of kaffekoppar by 0.15. That's it. Two steps become one mental move: remember that each kkp is just over a tenth of a liter.
Example: A recipe calls for 4 kkp of milk. Multiply 4 × 0.15, and you get 0.6 dm³ — in other words, 600 milliliters or 0.6 liters.
Converting Cubic Decimeter Back to Kaffekopp
Going the other direction, divide the dm³ value by 0.15, or multiply by roughly 6.67. For quick kitchen math, thinking of one liter as "about six and two-thirds coffee cups" gets you close enough for most recipes.
Example: You have 3 dm³ of stock and want to portion it into kkp servings. Divide 3 ÷ 0.15 to get 20 kkp. Done.
Why This Conversion Matters in Practice
Translating Nordic Recipes
Scandinavian baking has gone global — cinnamon buns, cardamom knots, and rye breads show up on menus everywhere. But many original recipes still list ingredients in kkp. Converting to dm³ (or liters) lets cooks outside Sweden follow along accurately with standard metric jugs and scales.
Scaling Recipes Up or Down
If you're doubling a batch of dough for a family gathering or multiplying a café recipe for commercial production, working in dm³ keeps the arithmetic clean. Multiplying 12 kkp by three batches is easier to verify when you first convert to 1.8 dm³ and scale from there.
Brewing and Beverage Work
Given its coffee-cup origins, it's fitting that the kaffekopp still shows up in beverage contexts. Whether you're portioning cold brew, batching glögg for a holiday market, or calibrating a percolator, expressing volumes in dm³ aligns with the liter markings on most brewing equipment.
Labelling and Compliance
Food businesses selling across borders typically must declare volumes in metric units. Knowing that a 2-kkp serving equals 0.3 dm³ helps you translate traditional portion sizes into compliant packaging labels without trial and error.

| 100 | 15.00 |
| 500 | 75.00 |
Tips for Accurate Volume Conversions
- Measure liquids at eye level. Place your jug on a flat surface and check the meniscus straight-on to avoid parallax errors.
- Don't swap dry and liquid measures blindly. A kkp of flour weighs far less than a kkp of sugar. When precision matters, convert the volume, then weigh the ingredient.
- Round sensibly. For home cooking, 0.15 dm³ per kkp is exact enough. For lab or industrial work, carry extra decimal places through your calculations.
- Watch for regional variations. Older Swedish texts occasionally treat the kaffekopp loosely. Modern standardized recipes stick to 150 ml, so confirm the source's era if results seem off.
The Bottom Line
Converting kaffekoppar to cubic decimeters comes down to one number: multiply kkp by 0.15 to get dm³. Since a cubic decimeter is simply another way of writing a liter, every conversion also tells you the liter equivalent — a detail that makes shopping, scaling, and labeling dramatically simpler.
