How the minutes to seconds converter works
Time converts through the second. Minutes, hours, days and weeks are exact multiples. A month is taken as the Gregorian average (30.436875 days) and a year as the Gregorian average (365.2425 days = 31,556,952 s); calendar months and leap years vary from these averages.
Australia is fully metric under the National Measurement Act 1960; imperial units appear only in trade with the US and in older documents.

Why does my stopwatch show hundredths?
Because human reaction time is around a fifth of a second, so hundredths are only meaningful with electronic timing.

1.5 minutes.
