Time Converter

A '13-hour' flight, a 30-day trial and a two-week notice period are the same span wearing different units — until you try to compare them. Conversions bite hardest at the edges: how many minutes is the meeting, how many days until the visa lapses, how much sleep is a whole weekend. This converter renders any duration from milliseconds to years in several units at once.

How is the Time Converter calculated?

Enter a duration and the unit it is written in. The headline answer converts it to the unit you chose, then four companions follow — minutes, weeks, months and years in the default view — with the factor row (1 day = 24 h) underneath. The conventions are fixed and stated on the form: a month averages 30.4375 days and a year is exactly 365.25 days, so twelve months always equal one year.

Formula

Convert through seconds: s = value × from factor, then target = s ÷ to factor. Exact factors: 1 min = 60 s · 1 h = 3,600 s · 1 day = 86,400 s · 1 week = 604,800 s. A month is the average calendar month (365.25 ÷ 12 = 30.4375 days = 2,629,800 s) and a year is the Julian year of 365.25 days, so 12 months equal exactly one year here.

Example

A 9-hour flight is 9 × 60 = 540 minutes and 9 ÷ 24 = 0.375 of a day. A three-week trip is 21 days or 504 hours. For subscriptions, one month averages 2,629,800 s = 730.5 hours, so a 30-day free trial (43,200 minutes) runs about 1.4% shorter than a calendar month — small until you renew annually.

Things to remember

Duration arithmetic is exact, but the assumptions are not: calendar months range from 28 to 31 days, and some contracts define a year as 360 days for billing. This page uses 30.4375-day months and 365.25-day years consistently — check which convention your document follows before quoting a figure in a lease or SLA.

Frequently Asked Questions

How many hours are there in three days?

72 hours. One day is exactly 24 hours, so multiply days by 24: three days give 72 h, ten days give 240 h, and a full week is 168 hours. Run it backwards by dividing — 1,000 hours is 41.67 days.

How many minutes are in a single week?

10,080 minutes. Seven days times 24 hours times 60 minutes gives 10,080, which is also 168 hours or 604,800 seconds. Divide any minute count by 10,080 to find out what fraction of a week it represents.

What does this calculator mean by one month?

The average calendar month: 365.25 days ÷ 12 = 30.4375 days, or 2,629,800 seconds. That convention keeps twelve months equal to one year exactly, unlike calendar months, which swing between 28 and 31 days depending on where you are in the year.

How long is 100 hours in days and hours?

4 days and 4 hours. Divide 100 by 24 to get 4.1667 days, then take the fraction — 0.1667 — and multiply by 24 to recover 4 hours. The same two-step method converts any unit into a mixed reading of big and small units.
