You found the perfect Scandinavian baking recipe. The ingredient list looks simple—until you hit "2 glas of milk." Your measuring spoons don't have a "glas" mark. Your measuring cup might not either. Now what?

This page solves that problem. Below, you'll learn what a tablespoon and a glas actually measure, how the two units relate, and how to switch between them without guesswork. Whether you're decoding an old Swedish cookbook or scaling a recipe for a crowd, you'll find everything you need right here.

What Exactly Is a Tablespoon?

A tablespoon is a small unit of volume used mostly in cooking and serving food. Its official symbol is Tbs, though you'll also see it written as "tbsp" or simply "tablespoon." In everyday kitchens, it's the workhorse spoon for oils, spices, syrups, and other ingredients added in modest amounts.

Here's the key thing to understand: a tablespoon measures volume, not weight. A tablespoon of honey and a tablespoon of water take up the same space, even though honey weighs more. That distinction matters when precision counts.

Tablespoon Standards Around the World

Not all tablespoons are identical, and this is where many conversion mistakes begin:

• Metric tablespoon: Exactly 15 milliliters. Used in most countries that follow the metric system, including Sweden.
• US customary tablespoon: Approximately 14.8 milliliters. Slightly smaller than the metric version.
• Australian tablespoon: Exactly 20 milliliters. Noticeably larger than the other two.

The differences seem tiny, but they add up. Twenty tablespoons of flour measured with Australian spoons versus US spoons creates a gap of more than 100 milliliters. When converting, always check which standard your source uses.

What Exactly Is a Glas?

The glas is a traditional Nordic household unit of volume, still common in Swedish, Norwegian, and Danish recipes. As the name suggests, it originally referred to a standard drinking glass. Over time, it settled into a defined measure: one glas equals 200 milliliters.

If you grew up outside Scandinavia, the glas may feel unfamiliar. Inside Nordic kitchens, though, it's as natural as the cup is in American baking. Grandmothers use it. Cookbooks use it. It's shorthand for "one ordinary glassful."

Where You'll Encounter the Glas

• Classic Swedish recipes: Older cookbooks and family recipes frequently list liquids like milk, cream, and water in glas.
• Baking traditions: Everything from semlor filling to blueberry soup may call for one or more glas.
• Everyday pouring: Since it matches a typical drinking glass, the unit doubles as a practical serving guide.

How Tablespoons and Glas Relate

Both units belong to the same parent measure: volume. That shared home is what makes conversion possible. They simply describe different scales—one tiny, one generous.

Using the metric tablespoon (15 ml) and the standard glas (200 ml), the relationship works out cleanly. One glas holds roughly 13⅓ tablespoons. Flip it around, and one tablespoon equals 0.075 glas.

In plain terms: it takes a heaping stack of thirteen-plus tablespoons to fill a single glas. That's why recipes written in glas feel so much quicker to prepare—you pour once instead of counting out spoonful after spoonful.

How to Convert Tablespoons to Glas by Hand

No calculator required. Follow these steps whenever you need to move from tablespoons to glas:

1. Start with your tablespoon count. Note the number listed in your recipe.
2. Divide by 13.33. This is the number of metric tablespoons in one glas.
3. Round sensibly. For cooking, rounding to two decimal places—or even the nearest quarter glas—is usually fine.

Example: A recipe calls for 40 tablespoons of stock. Divide 40 by 13.33 and you get almost exactly 3 glas. One quick pour replaces forty spoon measurements.

Going the other direction? Multiply the glas value by 13.33 to get tablespoons. Half a glas becomes roughly 6.7 tablespoons—easy to measure with a standard set of spoons.

Real-World Uses for This Conversion

When does this conversion actually earn its keep? More often than you'd think:

• Translating Nordic recipes: Convert glas-based ingredient lists into spoon-friendly steps when you lack a 200 ml glass.
• Scaling batch sizes: Doubling a recipe written in glas? Converting to tablespoons helps you portion precisely into containers.
• Tracking liquid intake: Some hydration guidelines use glass equivalents. Tablespoon measurements help when you're logging small sips, such as medication mixed with water.
• Cocktails and cordials: Homemade glögg and syrup recipes sometimes mix both units in a single ingredient list.

Quick Conversion Table: Tablespoons to Glas

The table below shows common tablespoon amounts converted to glas. Values use the metric tablespoon (15 ml) and the standard glas (200 ml).

Notice how quickly the glas column grows. Five hundred tablespoons sounds enormous—but it's just 37.5 glas, or under four liters. Large numbers shrink fast once you convert to bigger units.

Tips for Accurate Measuring

A few habits separate confident cooks from frustrated ones:

• Check your spoon's origin. If your tablespoon came from Australia, it holds 20 ml—not 15. Adjust accordingly.
• Level your spoons. For dry ingredients, sweep a straight edge across the top. Heaping tablespoons can inflate a measurement by 25% or more.
• Use liquid measures for liquids. A proper measuring jug beats a spoon for anything over a few tablespoons.
• Trust the tool for precision. Baking punishes approximation. Cooking forgives it. Know which situation you're in.

The Bottom Line

Converting tablespoons to glas comes down to one memorable fact: a glas holds about 13⅓ metric tablespoons, so each tablespoon is 0.075 glas. With that single ratio—and the table above—you can translate any Nordic recipe into measurements your kitchen already understands.
