The Standard System for Time Measurement

Time conversion is built upon fixed, universal constants. The International System of Units (SI) base unit for time is the **second**. All other units (minutes, hours, days) are multiples of the second.

Key Conversion Constants:

The relationships between the units are defined as:

  • $1 \text{ minute} = 60 \text{ seconds}$
  • $1 \text{ hour} = 60 \text{ minutes} = 3600 \text{ seconds}$
  • $1 \text{ day} = 24 \text{ hours} = 1440 \text{ minutes} = 86,400 \text{ seconds}$
For accurate calculations, this converter uses the **second** as the internal base unit for all intermediate steps.
