Tally Marks Converter

How it is calculated

The tool works with whole-number arithmetic. It rounds your entry to the nearest whole number, then computes groups = ⌊n ÷ 5⌋ (integer division) and remainder = n mod 5. The picture is built from those two numbers: one 'five' symbol (the tally group with the diagonal stroke) for each complete group, separated by spaces, followed by single-stroke symbols for the remainder. Zero is shown as the digit 0. The accepted range is 0 to 100,000; negative numbers and larger values return nothing. The marks are Unicode tally characters, so a device or font without that block may show empty boxes instead; the group and remainder counts still tell you the correct picture.

Common mistakes

• Counting the diagonal stroke as a sixth mark. In the standard system the crossing stroke is the fifth mark of the group, so one group is five and not six.
• Entering a decimal and expecting a partial stroke. The tool rounds to the nearest whole number first, so 4.6 becomes 5 and 4.4 becomes 4.
• Entering a value above 100,000, or a negative number. The tool gives no result outside the range 0 to 100,000.
• Reading a row of single strokes as a group. Only the crossed symbol means five; singles represent the one to four left over after the groups.
• Using the output as plain text in a place that lacks the font. Copy-pasting into some documents shows boxes, so check the display before printing.
