Enter a value, pick source and target units, and watch the result update in real time - seconds, minutes, hours, days, weeks, months, years. No setup, no sign-ups. This time converter calculator relies on standardized formulas: 120 minutes = 7,200 seconds; 1 week = 604,800 seconds. Need a quick calculation during study or work? Open the page and convert time quickly on the spot.

How to use the converter for time

Type the number you want to convert.
Pick the current unit (e.g., minutes).
Select the target unit (e.g., seconds).
Review the result and swap units if needed.

Swap directions at any moment to compare values both ways. Decimal inputs work for fractional hours or partial days. Rounding follows your input, keeping output practical for lab notes or classroom tasks.

Accuracy, formulas, and professional use cases

Conversions rest on clear formulas and widely accepted ratios: 60 seconds = 1 minute, 3,600 seconds = 1 hour, 86,400 seconds = 1 day. For long spans, context matters. One common year equals 31,536,000 seconds; leap years differ due to the extra day. Months vary in length, so we explain assumptions when a month converts to seconds.

Engineers, students, and analysts use the tool to check timing budgets, cycle durations, and reporting periods without manual errors. For time zones and universal time (UTC), remember that offsets and Daylight Saving Time can add a 1-hour shift - this page focuses on unit conversion, not clock timezone changes.

From	To	Factor	Example
second	minute	÷ 60	120 s = 2 min
minute	second	× 60	15 min = 900 s
minute	hour	÷ 60	180 min = 3 h
hour	minute	× 60	2.5 h = 150 min
hour	day	÷ 24	48 h = 2 d
day	hour	× 24	3 d = 72 h
day	week	÷ 7	14 d = 2 wk
week	day	× 7	1.5 wk = 10.5 d
day	second	× 86,400	2 d = 172,800 s
year (365 d)	second	× 31,536,000	1 y = 31,536,000 s
leap year (366 d)	second	× 31,622,400	1 y = 31,622,400 s
month (assumed 30 d)	second	× 2,592,000	1 mo ≈ 2,592,000 s
