Imperial teaspoon to Imperial pint

One imperial teaspoon equals approximately 5.919 mL — slightly larger than the US teaspoon (4.929 mL) and the metric teaspoon (5 mL).

An imperial teaspoon is approximately 5.92 mL; a metric teaspoon is exactly 5 mL. The metric teaspoon is now standard in UK cooking, medicine, and pharmacology.

The imperial teaspoon is obsolete in modern UK, Australian, and Canadian cooking, which all use the 5 mL metric teaspoon. It may appear in cookbooks published before the 1970s metrication period.

A culinary pinch — the amount you can hold between thumb and forefinger — is roughly 0.3–0.5 mL, or about 1/16 of a teaspoon. Professional recipe developers have measured this and found surprising consistency across people: the human fingertip geometry constrains how much fine powder you can grip. A "dash" (liquid) is about 0.6 mL, and a "smidgen" is half a pinch (~0.15 mL). These folksy terms survive in recipes because they map to real, repeatable volumes — within the tolerance that salt and spice measurements actually require.

The WHO recommended the 5 mL metric teaspoon for medication dosing in the 1970s to eliminate ambiguity between imperial (5.92 mL), US (4.93 mL), and other teaspoon sizes. A calibrated 5 mL oral syringe is now the recommended tool for all liquid medicines.

One imperial (UK) pint equals exactly 568.26 mL (20 imperial fluid ounces). A UK pint glass holds just over half a liter.

The UK is legally permitted to sell draft beer and cider in pints under exemptions to metrication rules. The pint is a protected official supplementary unit for draft alcohol. Milk may also be sold in pints.

Yes, an Irish pint is an imperial pint — 568 mL. A pint at an Irish pub is 20 imperial fluid ounces, identical to a UK pint.

In Australian pubs, a "pint" is technically 568 mL, but serving sizes vary by state. In South Australia and Western Australia, a "pint" is actually 425 mL. Australian glassware terminology is notoriously inconsistent.

One imperial pint equals exactly 20 imperial fluid ounces. A US pint equals 16 US fluid ounces. The fluid ounce sizes also differ slightly (28.41 mL imperial vs 29.57 mL US), compounding the pint size difference.
