The Time Converter is a free online tool that converts time values between seconds, minutes, hours, days, weeks and years instantly.

What is a time converter?
Time-based calculations show up everywhere — from project planning and billing in hours, to scientific measurements in seconds, to long-term planning in years. This tool converts between all common time units so you don't have to do the multiplication or division by hand. Manually multiplying or dividing by 60, 24, or 365 is easy to get wrong, especially when working with several time units at once.
