Convert from shot to ounce [UK, liquid]

Unit Definition (shot)
The shot is a traditional unit of liquid volume. The term "shot" is often used informally to mean "a small serving." In the U.S. a shot is legally equal to one fluid ounce or 29.574 milliliters. However, many bartenders use larger shot glasses holding 1.25 fluid ounces (37.0 milliliters), and some shot glasses hold the same as a jigger: 1.5 fluid ounces or 44.4 milliliters.

Unit Definition (ounce [UK, liquid])

A British fluid ounce weighs exactly one ounce at a specified temperature and pressure.
