Our free online time converter is the most accurate tool for converting time and duration units between different systems. The calculator supports over 40 formats, including the smallest units (nanoseconds) to the largest (millennia).
Most Popular Time Conversions
Seconds to Minutes (s → min): The most common time unit conversion. 1 minute equals 60 seconds. Used in sports, cooking, science, and daily life. Conversion formula: minutes = seconds ÷ 60. Example: 300 seconds ÷ 60 = 5 minutes.
Minutes to Hours (min → h): Important conversion for time planning and event duration calculations. 1 hour equals 60 minutes. Used in work accounting, education, medicine. Formula: hours = minutes ÷ 60. Example: 150 minutes ÷ 60 = 2.5 hours.
Hours to Days (h → d): Conversion for work time calculations and project planning. 1 day equals 24 hours. Used in logistics, manufacturing, project management. Formula: days = hours ÷ 24. Example: 72 hours ÷ 24 = 3 days.
Milliseconds to Seconds (ms → s): Important conversion in programming, electronics, and precise sciences. 1 second equals 1000 milliseconds. Used in computer science, physics, medicine. Formula: seconds = milliseconds ÷ 1000.
Days to Weeks (d → wk): Practical conversion for vacation planning, projects, and educational programs. 1 week equals 7 days. Used in HR activities, education, and time management. Formula: weeks = days ÷ 7. Example: 21 days ÷ 7 = 3 weeks.
Years to Months (yr → mo): Conversion for long-term planning and financial calculations. 1 year equals 12 months. Used in banking, insurance, career planning. Formula: months = years × 12. Example: 2.5 years × 12 = 30 months.
Time Measurement Systems
International System of Units (SI): Base time unit is the second. Derived units are formed with prefixes: nanoseconds (10⁻⁹ s), microseconds (10⁻⁶ s), milliseconds (10⁻³ s). Used in science, technology, and official standards. The second is defined as the duration of 9,192,631,770 periods of radiation from cesium-133 atom.
Calendar System: Based on Earth's astronomical cycles. Includes: minutes (60 s), hours (60 min), days (24 h), weeks (7 d), months (≈30.44 d), years (365.25 d). Used in civilian life, planning, and history. Calendar year accounts for leap years for calculation accuracy.
Special Units: Specific units for separate fields. Jiffy (1/100 second) in animation, shake (10 nanoseconds) in high-energy physics, svedberg (10⁻¹³ second) in atomic physics. Planck time (5.39 × 10⁻⁴⁴ seconds) - the smallest theoretically possible time unit in physics.
Work Time: System for accounting labor activities. Includes work hours, days, weeks, months. 1 work day typically equals 8 hours, work week - 40 hours (5 work days). Used in HR, payroll systems, and project planning.

Multimedia and Entertainment: Audio and video synchronization, content duration calculation, air time planning. Converting between frames, seconds, and minutes in video editing. Also used in gaming industry for timer settings and animations.
Calendar Calculation Features
Leap Years: Our calculator uses an average value of 365.25 days per year, accounting for leap years that occur every 4 years. This ensures accuracy of long-term calculations and considers the Gregorian calendar used in most countries worldwide.
Variable Month Length: Calculations use an average value of 30.4375 days per month (365.25 ÷ 12). This accounts for different numbers of days in various months from 28 to 31 days. February has 28 days in regular years and 29 days in leap years.
Weekly Cycles: A week always consists of 7 days regardless of calendar month. This makes conversion between days and weeks simple and accurate. Weekly cycle doesn't depend on astronomical phenomena and remains constant.
Time Zones: The calculator works with absolute time values without considering time zones. For accurate calculations between different time zones, specialized time zone tools are recommended.
Tips for Accurate Conversion
Choosing Appropriate Precision: Use maximum precision for scientific calculations, 2-3 decimal places are sufficient for everyday needs. When working with milliseconds in programming, precision to microseconds is important. In financial calculations, precision to the day is usually sufficient.
Usage Context: Consider industry specifics. Medicine requires critical timing precision, sports need precision to hundredths of seconds, astronomy to nanoseconds. Manufacturing requires minute precision, logistics needs hour precision.
Result Rounding: Avoid premature rounding of intermediate results. Round only the final result to the required precision for specific application. Use mathematical rounding for maximum accuracy.
Logic Verification: Always check if the obtained result is logical. For example, 3600 seconds should give 1 hour, and 86400 seconds should give 1 day. If the result seems implausible, check input data and selected unit system.
Working with Large Numbers: When converting large time periods (years, decades), consider possible accumulation errors. Use scientific notation for very large or very small time values.
Calculation Precision Preservation: Our calculator uses high-precision algorithms to minimize rounding errors. For critically important calculations, verification with several independent methods is recommended.
