What is an imperial pint?

An eighth of an imperial gallon, 568.26125 ml exactly, and still the legal measure for draught beer and doorstep milk in the UK. A US pint is 473 ml, which is why a British pint glass holds noticeably more.

What is a US teaspoon?

One third of a tablespoon, about 4.93 ml. A metric teaspoon is a round 5 ml, which is why recipes rarely notice the difference.

How many US teaspoons are in an imperial pint?

One imperial pint is 115.29119 US teaspoons. Going the other way, one US teaspoon is 0.0086736894 imperial pints. Both figures come from the same defined relation rather than from a measurement, which is why they are the same today as they were in 1959.

The whole group — 20 units with their symbols and the size of each one in liters — is on the conversion index, along with every pair it makes. The table above already gives each of them relative to an imperial pint.
