Decimal time, sometimes referred to as metric time, uses a base 100 system instead of a base 60 system. Each decimal hour has 100 decimal minutes and each decimal minute has 100 decimal seconds, whereas a standard hour has 60 minutes and a standard minute has 60 seconds. Each decimal second equals 0.864 standard seconds. To convert from decimal time to standard seconds, convert the decimal time in hours, minutes and seconds to decimal seconds and then convert to standard seconds.
