However, in the UK, a pint is equivalent to 20 ounces.</s>\ <s>[INST] can you explain the difference between metric and imperial measurements? [/INST] The primary difference between metric and imperial measurements is that the metric system is based on units of 10 (ex. 10, 100, 1000, 1/100, 1/1000 etc.) while the imperial system is primarily based on 1/2s (ex. 1/2, 1/4, 1/8 etc.) although there are some exceptions to the imperial system, such as there are 12 inches in a foot. The imperial system originates from the Roman Army, where the measurement of a mile came from a combination of the measurement of a Roman soldier's sandaled foot, and the Latin 'mille passus' which translates to 1000 paces.</s>
