About time conversions
Time conversions appear constantly in programming, project planning, fitness and billing — wherever a duration in one unit needs restating in another. While seconds, minutes, hours and days have fixed ratios, longer spans are best computed through a common base of seconds for accuracy.
The converters below move between milliseconds, seconds, minutes, hours, days and weeks using exact factors, so durations stay precise from sub-second timing to multi-week schedules.
