Tablespoons (Tbs) to Kannor (kanna) conversion

What is Tablespoons?

Tablespoon is a unit of volume primarily used in cooking and measuring ingredients. It's a common unit in recipes, especially in the United States, the United Kingdom, and other countries influenced by their systems of measurement. Let's delve into its definition, history, and usage.

Definition and Equivalencies

• US Tablespoon: Approximately 14.8 mL (milliliters) or 0.5 US fluid ounces.
• UK Tablespoon: Traditionally 17.7 mL (but often considered to be 15 mL for cooking purposes to align with US measurements).
• Australian Tablespoon: 20 mL.

It's important to be aware of these differences, especially when following recipes from different regions. For practical purposes, you can often assume the following conversions in cooking:

• 1 Tablespoon (US) ≈ 3 teaspoons
• 1 Tablespoon (US) ≈ 1/16 cup (US)

Historical Context

The origin of the tablespoon can be traced back to silverware and dining customs. Originally, spoons were used for both eating and measuring. Over time, standardization efforts led to more defined units of volume, but the tablespoon retained its association with cutlery. The exact history of its formal definition is complex, but it evolved alongside other customary units.

Practical Applications and Examples

Tablespoons are widely used in cooking for measuring both liquid and dry ingredients. Here are some examples:

• Baking: A recipe might call for 2 tablespoons of butter or 1 tablespoon of vanilla extract.
• Cooking Sauces and Dressings: Salad dressings often use tablespoons of olive oil, vinegar, or other flavorings.
• Medication: Liquid medications are sometimes prescribed in tablespoon doses.
• Coffee: Some people use tablespoon to measure out amount of coffee grounds they want to use.

Examples:

• 1 Tablespoon of Honey: Approximately 21 grams.
• 2 Tablespoons of Peanut Butter: Approximately 32 grams.
• 3 Tablespoons of Water: Approximately 44.4 mL (using the US definition).

Conversions

Converting between tablespoons and other units of volume is a common task in the kitchen. Here's a summary of useful conversions:

• Tablespoons to Milliliters (mL):
  • US: $mL = Tablespoons * 14.8$
  • Australian: $mL = Tablespoons * 20$
• Tablespoons to Fluid Ounces (fl oz):
  • US: $fl oz = Tablespoons * 0.5$
• Tablespoons to Teaspoons (tsp):
  • $tsp = Tablespoons * 3$
• Tablespoons to Cups:
  • US: $Cups = Tablespoons * \frac{1}{16}$

What is Kannor?

Kannor is the plural of kanna, an old Swedish unit of volume used for both liquids and dry goods before Sweden adopted the metric system. It was one of the most common everyday measures in Sweden for centuries, especially for spirits and other liquids.

Definition of Kanna

Following the Swedish measurement regulations of 1665, one kanna was standardized at approximately 2.617 litres.

$$1 \text{ kanna} \approx 2.617 \text{ L} = 2617 \text{ mL}$$

The kanna was part of a coherent system of Swedish volume units. Its subdivisions and multiples included:

• 1 kanna = 2 stop
• 1 kanna = 8 kvarter
• 1 kanna = 32 jungfrur
• 1 kanna = 1/48 tunna (barrel)

Origin and Formation

The kanna originated as a practical measure tied to common containers used for storing and transporting goods. Sweden brought its many local measures under a single national standard with the ordinances of 1665, which fixed the kanna at about 2.617 litres. The unit was used throughout Sweden (and Finland, then part of the Swedish realm) for trade in liquids such as beer, milk, and spirits, as well as for some dry goods.

Historical Significance and Usage

For more than two centuries the kanna was a mainstay of Swedish commerce and daily life. Merchants, brewers, and farmers measured and sold goods by the kanna and its subdivisions. The unit was gradually phased out as Sweden transitioned to the metric system, which became mandatory in 1889. After that, litres replaced kannor in everyday and legal use.

Conversions

Using the 1665 value of 2.617 litres:

• 1 kanna ≈ 2.617 litres
• 1 kanna ≈ 0.691 US gallons
• 1 kanna ≈ 0.576 Imperial gallons
• 100 kannor ≈ 261.7 litres

To convert a volume in kannor to litres:

$$\text{Volume in Liters} = \text{Volume in Kannor} \times 2.617$$

Laws and Associated Figures

The kanna was defined by Swedish royal measurement ordinances rather than by any single individual. Its standardization in 1665 and its eventual replacement by the metric system in 1889 reflect Sweden's long effort to bring consistency to weights and measures.
