What is this?
A time duration converter converts between time units: seconds, minutes, hours, and days. It uses standard conversions: 1 minute = 60 seconds, 1 hour = 60 minutes, 1 day = 24 hours. Enter a value in one unit and get the equivalent in another. Useful when different systems or tools use different units—for example, some APIs return seconds while you need hours. The conversion is instant and handles large values (like total seconds in a year) without rounding errors.
When to use
Use for time tracking, converting workout durations, scheduling, or any task involving time units. Example: 90 minutes = 1.5 hours; 86400 seconds = 1 day. Developers convert API timestamps. Coaches convert workout times between formats. Project planners convert between hours and days. Video editors work in frames and seconds. Anyone dealing with multiple time units needs quick conversion.
