Hex Multiplication Table Generator

Generates a configurable NxN multiplication table (default 0-F) rendered as a real HTML table, with the row headers, column headers, and every cell value all shown in hexadecimal; each cell is computed as row x column in decimal, then hex-formatted. A free online tool from Staaarter, right in your browser.

Overview

Introduction

Working in hexadecimal regularly means eventually wanting the same kind of quick-reference table you'd use for decimal multiplication, but with everything, inputs and results, shown in hex instead.

This tool generates exactly that: a configurable NxN grid where the row and column headers and every cell's product are all displayed as hexadecimal numbers.

What Is Hex Multiplication Table Generator?

A multiplication table where both axes are labeled with hex digits (0-F by default, extendable to two-digit hex headers for larger sizes) and every cell shows the product of its row and column header, computed in decimal and then converted to hex for display.

It's rendered as a real HTML table (not ASCII art), since a genuine table element is the clearest way to present a two-axis reference grid like this.

How Hex Multiplication Table Generator Works

For a table of size N, the headers are the hex representations of 0 through N-1.

Every cell at row r and column c is computed as `r * c` in ordinary decimal arithmetic, then the result is converted to its uppercase hexadecimal string for display, so the underlying math is standard multiplication even though everything you see is hex.

When To Use Hex Multiplication Table Generator

Use it as a quick-reference chart while doing hex arithmetic by hand, programming low-level code, or studying number systems.

It's also handy for spot-checking a hex multiplication result you've computed manually, or for building intuition about how hex products compare to their decimal equivalents.

Features

Advantages

  • Fully deterministic and instantly readable as a genuine table element, not an ASCII approximation.
  • Size is configurable from a small quick-reference chart up to a larger 32x32 table.
  • Headers and cell values are both in hex, avoiding any decimal-to-hex mental translation while reading the table.

Limitations

  • Capped at 32x32 to keep the table a reasonable size to render and read.
  • Cell values beyond a single hex digit (anything 16 or greater) show as two-plus hex digits without extra padding, so column widths vary slightly by value.

Examples

A mid-table cell

Input

row 3, column 4 (default 0-F table)

Output

C

3 x 4 = 12 in decimal, which is 0xC in hexadecimal.

The largest cell in the default table

Input

row F, column F (default 0-F table)

Output

E1

15 x 15 = 225 in decimal, which is 0xE1 in hexadecimal.

Best Practices & Notes

Best Practices

  • Stick with the default 0-F size for a quick single-hex-digit reference chart; only increase the size if you specifically need two-digit hex row/column headers.
  • Cross-check a manual hex multiplication against the corresponding cell here as a sanity check.

Developer Notes

Cell values are computed with ordinary JavaScript number multiplication in decimal (`r * c`), then formatted with `.toString(16).toUpperCase()`; there's no hex-native multiplication algorithm involved, since converting to decimal, multiplying, and converting back is both simpler and exactly equivalent for integers in this size range.

Hex Multiplication Table Generator Use Cases

  • Quick-reference chart while doing hex arithmetic by hand
  • Spot-checking a manually computed hex multiplication result
  • Teaching or learning how numeric products look when displayed in base 16

Common Mistakes

  • Reading a header digit as decimal instead of hex, e.g. treating column "A" as 10 columns further right than it actually is.
  • Expecting cell values to be zero-padded to a fixed width; they're shown as their plain hex representation, which varies in digit count.

Tips

  • Use the default 0-F size for the most common quick-reference use case; it covers every single-hex-digit product.
  • Increase the size only when you need two-digit hex row/column headers for a wider reference range.
