Time Converter – Convert Seconds, Minutes, Hours, Days & More

Convert Time Units Instantly

Enter any time value in the field above, select your input and output units, and get instant conversion results. The calculator supports all standard time units from seconds to years.

Supported Time Units

Our time converter supports the following units:

• Seconds (s) – Base unit of time
• Minutes (min) – 60 seconds
• Hours (h) – 60 minutes
• Days (d) – 24 hours
• Weeks (wk) – 7 days
• Months (mo) – Average of 30.44 days
• Years (yr) – 365 days (standard year)

Month and year conversions use standard averages since these units vary in actual length. For exact calculations involving specific months or leap years, additional precision may be needed.

How Time Conversion Works

Time conversion works by understanding the fixed relationships between time units. Each minute contains exactly 60 seconds, each hour contains exactly 60 minutes, and each day contains exactly 24 hours. These conversions are precise and consistent.

However, conversions involving months and years use standard averages because these units vary in length. A standard month is calculated as 30.44 days (365 ÷ 12), and a standard year is 365 days. For most practical purposes, these averages provide sufficiently accurate results.

The converter uses seconds as the base unit for most calculations. When you convert between larger units like hours and days, the tool first converts your input to seconds, performs the calculation, then converts to your desired output unit. This ensures accuracy across all conversion types.

Common Time Conversion Formulas

Use these formulas to convert between common time units:

Basic conversions:

• Minutes = Seconds ÷ 60
• Hours = Minutes ÷ 60
• Days = Hours ÷ 24
• Weeks = Days ÷ 7
• Months = Days ÷ 30.44
• Years = Days ÷ 365

Reverse conversions:

• Seconds = Minutes × 60
• Minutes = Hours × 60
• Hours = Days × 24
• Days = Weeks × 7
• Days = Months × 30.44
• Days = Years × 365

These formulas work for any whole or decimal value. The converter applies these formulas automatically to give you instant results.

Frequently Asked Questions About Time Conversion

What is a time converter?

A time converter is a tool that transforms time values from one unit to another, such as converting seconds to minutes or hours to days. The converter performs automatic calculations using standard time unit relationships to provide instant, accurate results.

Are time conversions always exact?

Conversions between seconds, minutes, hours, days, and weeks are always exact because these units have fixed relationships. Conversions involving months and years use standard averages (30.44 days per month, 365 days per year) and may be slightly approximate depending on the specific dates involved.

What is the smallest unit of time?

In everyday use, the second is the standard smallest unit. However, time can be measured in smaller units like milliseconds (1/1000 of a second), microseconds (1/1,000,000 of a second), and even smaller divisions used in scientific applications.

Why do months have different lengths?

Months vary in length due to the historical development of calendars, ranging from 28 days (February in common years) to 31 days. For time conversion purposes, a standard month is calculated as approximately 30.44 days, which is the average length across all months (365 days ÷ 12 months).

Is a year always 365 days?

A standard year is 365 days, but a leap year contains 366 days and occurs every four years (with some exceptions). For general time conversions, 365 days is used as the standard year length.

Can I convert decimal values?

Yes, this time converter accepts decimal values. For example, you can convert 1.5 hours to minutes (90 minutes) or 2.5 days to hours (60 hours). Decimal conversions are useful for precise calculations.

Is this time converter accurate?

Yes, this converter uses precise mathematical formulas for all conversions. Fixed unit conversions (seconds, minutes, hours, days, weeks) are exact, while month and year conversions use industry-standard averages for consistent results.
