Convert Time to Hex Time

Convert Time to Hex Time lets you transform standard hh:mm time into a hexadecimal representation based on the total number of minutes since midnight. This is especially useful for developers, system timers, or anyone working with hex-based time tracking systems.

How to Use:

  1. Enter one or more times into the left box using hh:mm format (e.g., 15:45).
  2. You can enter multiple times on separate lines to convert them all at once.
  3. The right-hand box shows the hex value of total minutes past midnight for each time.
  4. Use Copy Output to grab the result or Export to File to download it.
  5. Select a local file using Choose File to import times directly.
  6. Click Clear All to reset everything instantly.

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
