Time Converter

Time Converter converts between seconds, minutes, hours, days, weeks, and common fractions thereof. It is useful when APIs return durations in seconds, logs show milliseconds, and your brain thinks in hours and minutes.

Computing time differences and durations across unit systems — especially in code — is a common source of off-by-60 or off-by-3600 bugs. A quick conversion check catches these before they reach production.

Tip: For sub-second precision such as milliseconds or microseconds, floating-point rounding may affect the last digit at high precision. For timing-critical systems, store and convert in integer milliseconds to avoid precision loss.
