When a Carnival fete in Port-of-Spain says it starts at 17:30, your auntie still asks: 'Boy, that's 5:30 in the EVENING, right?' Two notations, the same moment in time. The same goes for measuring 1.5 km of road in Georgetown, that's 1500 m, 150 000 cm, or 1 500 000 mm. The skill of switching between systems and rounding sensibly is at the heart of every CSEC question.
