Why does the UK teaspoon have different volumes?

The UK teaspoon historically was defined as 1/6 of an imperial fluid ounce (~4.736 mL), but many modern recipes use the metric 5 mL teaspoon, so both values coexist depending on the source.

Can I use this conversion for all tablespoons worldwide?

No, tablespoon sizes vary by country. This tool assumes the metric tablespoon standard of 15 mL; other sizes like Australia's 20 mL tablespoon need separate consideration.

Is teaspoon dosing reliable for medicines?

Using teaspoons for household doses is common but less precise than dedicated dosing devices, so specialized tools are recommended for accurate medication measurement.
