Find a Millimeter Size on an Inch Tape

These worked examples include an enlarged ruler diagram, the tape marks on either side, and the difference caused by rounding.

How to Use This MM to Inches Chart

Find your millimeter value in the left column. The right column gives the inches in decimals (rounded to 4 places). Orange rows mark exact whole inches — for example, 2″ is exactly 50.8 mm. Follow a linked value for a worked example or its detailed row in the complete reference below.

The formula behind every row is simple: inches = millimeters ÷ 25.4.

MM to Inches Chart FAQ

How many inches is 1 mm?

1 millimeter equals 0.03937 inches. Put another way, there are 25.4 millimeters in one inch, so each millimeter is just under 1/25 of an inch.

How do I convert mm to inches without a chart?

Divide the millimeter value by 25.4. For example, 100 mm ÷ 25.4 = 3.9370 inches. To get a fraction, multiply the decimal part by 16 and round to the nearest whole number for sixteenths.

Why is 2 inches not listed as 51 mm?

Because 2 inches is exactly 50.8 mm, which falls between 50 mm and 51 mm. It is shown as a highlighted orange row in the chart. 51 mm is slightly more than 2 inches (2.0079 inches). For tape-measure fractions, use our inches to mm chart.

Can I print this mm to inches chart?

Yes. Click the Print Chart button at the top of the page. The page is set up to print cleanly without menus or ads, and you can choose Save as PDF in the print dialog to keep a digital copy.

Complete MM to Inches Reference: 1–300 mm

Find every whole millimeter here. Decimal inches are rounded to four places; fractions are rounded to the nearest 1/64 inch. Each row also shows how much longer or shorter the fraction is than the original metric measurement. These differences describe rounding, not the accuracy of a measuring tool.

For an arbitrary decimal measurement, use the interactive converter. For a worked example, follow a linked size.
