About Imperial tablespoon (imp tbsp)
The imperial tablespoon is a unit of volume equal to approximately 17.758 milliliters, defined as five-eighths of an imperial fluid ounce. It is used in older UK and Commonwealth cooking recipes. The imperial tablespoon is larger than the US tablespoon (14.787 mL) but smaller than the Australian tablespoon (20 mL). Modern British and Commonwealth recipes have replaced it with the 15 mL metric tablespoon, but it persists in pre-metrication cookbooks.
Older British recipe books specify tablespoons of approximately 17.8 mL — larger than a US tablespoon but smaller than an Australian one.
About Deciliter (dl)
A deciliter (dL) is one tenth of a liter (0.1 L), equal to 100 milliliters. It is used in clinical laboratory medicine for reporting blood test results (blood glucose, haemoglobin, cholesterol in mg/dL or g/dL), in European nutrition labeling, and in Scandinavian cooking recipes. Despite its limited everyday use as a liquid measure, the deciliter is one of the most medically significant volume units — nearly every blood test result references it.
Blood glucose is reported in mg/dL. A small yoghurt pot or juice glass holds roughly 1–2 dL.
Imperial tablespoon – Frequently Asked Questions
How many milliliters is an imperial tablespoon?
One imperial tablespoon equals approximately 17.758 mL — larger than the US tablespoon (14.79 mL) and smaller than the Australian tablespoon (20 mL). Modern UK metric tablespoons are standardized at 15 mL.
What is the most common baking disaster caused by tablespoon size confusion?
Leavening failure. Baking powder and baking soda are measured in tablespoons, and the difference between a US tablespoon (14.8 mL), an imperial tablespoon (17.8 mL), and an Australian tablespoon (20 mL) is 15–35%. Too much baking soda makes bread taste metallic and soapy; too little and it does not rise. A British grandmother's scone recipe used in an American kitchen with US tablespoons will under-leaven by 20%. Professional bakers avoid this entirely by weighing leavening agents in grams.
Is the imperial tablespoon still used in UK cooking?
No. Modern UK cooking uses 15 mL metric tablespoons. The imperial tablespoon (17.76 mL) appears only in pre-1970s British cookbooks.
How many imperial teaspoons are in an imperial tablespoon?
One imperial tablespoon equals 3 imperial teaspoons (each ≈ 5.92 mL), giving 3 × 5.92 = 17.76 mL. The same 3:1 ratio as in US and metric systems, though the absolute sizes differ.
What is the standard tablespoon size in Australia?
The Australian tablespoon is 20 mL — the largest of the major English-language cooking tablespoons. Australian recipes therefore use fewer tablespoon counts than US or UK recipes for the same volume.
Deciliter – Frequently Asked Questions
What is a deciliter used for in medicine?
Deciliters are the standard reference volume for blood test results. Blood glucose is reported in mg/dL, haemoglobin in g/dL, and cholesterol in mg/dL. Normal fasting blood glucose is 70–99 mg/dL.
How many milliliters are in a deciliter?
One deciliter (dL) equals 100 milliliters (mL). Since 1 dL = 0.1 L and 1 mL = 0.001 L, there are exactly 100 mL per dL.
Is the deciliter used in cooking?
Yes, in Scandinavia (Sweden, Norway, Denmark) recipes commonly list liquid ingredients in deciliters. 1 dL is roughly 6–7 tablespoons or just under half a US cup.
What is a normal blood glucose reading in mg/dL?
A normal fasting blood glucose is 70–99 mg/dL. Pre-diabetes is 100–125 mg/dL. Diabetes is diagnosed at ≥126 mg/dL on two separate tests. Post-meal levels should be below 140 mg/dL in non-diabetics.
How does a deciliter compare to a cup?
One deciliter (100 mL) is roughly 0.42 US cups. Conversely, one US cup is about 2.4 dL. For Scandinavian recipes, 1 dL ≈ just under half a cup.
