Meaning & usage

⅕ is one fifth — 0.2, 20% — one of the 'fifths' family (⅖ ⅗ ⅘) built into Unicode for neat recipes and data. Single-character fractions like this one are called vulgar fractions: pre-composed glyphs that keep measures on one line and stop them splitting across line breaks.

They come from metal type, where a tiny cast fraction saved the compositor from stacking small numerals. Modern fonts include the common set — halves, quarters, thirds, fifths and eighths — all gathered in this page's variants grid.

Frequently asked questions

How do I type ⅕ on a keyboard?

There is no standard Alt code for ⅕. Copy it from this page and paste it — in Word you can also type 2155 then press Alt+X.

Why is it called a vulgar fraction?

'Vulgar' is the old Latin for 'common' — a vulgar fraction is an ordinary fraction written as one quantity over another, as opposed to a decimal.

Why does ⅕ sometimes show as a box or question mark?

The box (called tofu) means the device or font viewing it has no drawing for U+2155 (Vulgar Fraction One Fifth). The character itself is fine — try a different font or a newer device, or use one of the variants on this page.

Is the One Fifth Fraction free to use?

Yes. ⅕ is a standard Unicode text character published in the Unicode Character Database. You may use it in personal and commercial documents, designs and products without permission or payment.
