Why does the UK teaspoon volume differ?

Historically, the UK teaspoon was defined as one-sixth of an imperial fluid ounce (~4.736 mL), but many modern uses apply the metric teaspoon of 5 mL, so both standards exist.

Is the liter an SI unit?

The liter is not a base SI unit but is accepted for use with the SI system and represents a volume equal to one cubic decimeter.

Can I rely on this converter for precise medicinal dosing?

While this converter provides useful estimates, specialized dosing devices are recommended for accurate liquid medicine measurements.
