Ever tried to follow a Swedish recipe that calls for “2 glas mjölk” and wondered how many tablespoons that really is? You’re not alone. Converting between the traditional kitchen units “glas” (glass) and “msk” (matsked, i.e., tablespoon) can be the difference between a perfect batter and a soggy mess.

Exact Conversion Factor

Within the volume measure, the relationship is fixed:

1 glas = 13.3333 msk

The reverse is equally simple: 1 msk = 0.075 glas. Both numbers are derived from the standard metric definitions (1 glas = 200 ml, 1 msk = 15 ml).

How the Units Are Defined

Glas (glas)

A “glas” is a traditional Swedish drinking glass. It is officially defined as 200 milliliters (0.2 liters). The unit is used for both beverages and liquid ingredients in cooking.

Matsked (msk)

“Matsked” translates to “tablespoon.” One matsked equals 15 milliliters. It is the standard spoon‑size measurement for sauces, spices, and other small‑volume ingredients.

Why This Conversion Matters

• Recipe accuracy: Many classic Swedish dishes list ingredients in glas and matsked. Knowing the exact factor lets you scale recipes up or down without guesswork.
• International cooking: If you’re using a foreign cookbook that references these units, the conversion keeps your results consistent.
• Portion control: Whether you’re measuring a drink for a party or a sauce for a dinner, the conversion helps you serve the right amount.

Conversion Formula

To go from glas to matsked, multiply by 13.3333:

msk = glas × 13.3333

To reverse the process, divide by the same factor (or multiply by 0.075):

glas = msk × 0.075

Worked Example

Imagine a recipe that requires 3 glas of cream. How many matsked is that?

1. Start with the factor: 1 glas = 13.3333 msk.
2. Multiply: 3 glas × 13.3333 = 40.0000 msk.

Result: 3 glas ≈ 40 msk. You can now measure the cream with a standard tablespoon set.

Practical Tips for Quick Conversions

• Keep a small cheat‑sheet in your kitchen: “1 glas ≈ 13 ½ msk.” The half‑tablespoon is easy to estimate.
• If you only have a 10 ml spoon, remember that 1 msk = 1.5 × 10 ml. So 13.3333 msk ≈ 20 × 10 ml.
• For large batches, round to the nearest whole number of matsked and adjust the final taste if needed.

Glas to Matsked Conversion Table

Each row applies the same rule: multiply the number of glas by 13.3333 to get matsked (rounded to 4 decimal places).

Common Mistakes to Avoid

• Mixing metric and imperial: Do not substitute a US “cup” (236 ml) for a “glas” (200 ml) without adjusting the factor.
• Ignoring rounding: Using 13 msk instead of 13.3333 msk can accumulate error in large recipes.
• Forgetting the reverse factor: When converting back, remember 1 msk = 0.075 glas, not 0.07.

Conclusion

Understanding that 1 glas = 13.3333 msk unlocks precise, hassle‑free cooking with Swedish measurements. Use the formula, refer to the table, and you’ll never be stuck guessing again. Ready to perfect your next recipe? Grab a tablespoon, measure confidently, and enjoy the results.
