Time Converter: Complete Guide with Formulas and Real-World Applications
What is Time Conversion?
Time conversion is the process of changing a measurement from one unit of time to another. This is essential in many fields including science, engineering, scheduling, computing, and daily life. Common systems include metric units (seconds, minutes, hours) and larger time units (days, weeks, months).
The conversion is based on fixed relationships between units. For example, 1 minute equals 60 seconds, 1 hour equals 60 minutes, and 1 day equals 24 hours according to the international standard.
Time Conversion Formulas
The general formula for time conversion is:
Converted Value = (Input Value × Target Factor) / Source Factor
Using seconds as the base unit, the conversion from unit A to unit B is:
- Step 1: Convert input value to seconds: Value × FactorA
- Step 2: Convert seconds to target unit: (Step 1 result) / FactorB
How to Convert Time Units
To convert between time units:
- Identify the units: Determine the original unit (e.g., hours) and the target unit (e.g., minutes)
- Find conversion factors: Look up how many base units (seconds) each unit represents
- Apply the formula: Multiply by the source factor and divide by the target factor
- Calculate: Perform the arithmetic to get the converted value
Our calculator automates this process, providing accurate conversions instantly.

FAQs
How many seconds are in a day?
There are 86,400 seconds in a day. This is calculated as 24 hours × 60 minutes × 60 seconds = 86,400 seconds.
How many minutes are in a year?
There are 525,600 minutes in a regular year (365 days × 24 hours × 60 minutes) and 527,040 minutes in a leap year.
How do I convert hours to seconds?
To convert hours to seconds, multiply the time in hours by 3600. For example, 3 hours × 3600 = 10,800 seconds.
What is the difference between a sidereal day and a solar day?
A solar day (24 hours) is the time it takes for the Sun to return to the same position in the sky, while a sidereal day (23 hours 56 minutes 4 seconds) is the time it takes Earth to complete one rotation relative to the stars.
Why are there 60 minutes in an hour?
The division of time into 60 minutes per hour and 60 seconds per minute comes from the ancient Sumerian and Babylonian number systems, which were based on the number 60 (sexagesimal system).
