What Convert Time to Hex Time can do:

  • Converts each time into hex by calculating (hours × 60 + minutes) and converting it to hexadecimal.
  • Supports batch processing of multiple times per line.
  • Pads hexadecimal values to 3 digits (e.g., 0A5 for 165 minutes).
  • Validates input and highlights lines that don’t match hh:mm or exceed real time bounds.
  • Automatically updates output and highlights changes.

Example:

00:00
01:30
12:00
15:45
23:59

Becomes:

00:00 = 000
01:30 = 096
12:00 = 2D0
15:45 = 3A5
23:59 = 59F

Common Use Cases:

Convert Time to Hex Time is perfect for anyone encoding time in hexadecimal format from embedded system developers to game designers working with custom clocks. It’s also a neat way to visualize time differently and add a techie twist to everyday timestamps.
