100 centimeters = 39.37 inches (3 feet and 3.37 inches), or 39 3/8" as a fraction. Use the copy buttons below to grab the exact format you need.
The centimeter (cm) and the inch (in) are two of the most common units of length in everyday use. Centimeters belong to the metric system — used by most of the world — while inches are part of the imperial system, still widely used in the United States, UK (for personal measurements), and Canada. Converting between the two is straightforward: 1 inch = 2.54 cm, so to go from centimeters to inches you divide by 2.54. For 100 cm, that gives you 100 ÷ 2.54 = 39.37 inches.

Here are three practical situations where knowing that 100 cm equals 39.37 inches makes a real difference.
You're sourcing a 100 cm shelf bracket, curtain rod, or cabinet panel from a European supplier — but your local hardware store uses imperial measurements. That 100 cm piece is 39.37" (39 3/8"), which you'd round to the nearest standard US lumber or hardware size. For framing or trim work in the US, knowing the fractional equivalent (39 3/8") is especially useful since US tape measures mark in 1/16" increments.
International clothing brands — particularly European and Asian labels — list garment dimensions in centimeters. If a jacket has a 100 cm chest, sleeve, or back length, that translates to roughly 39.37" (3 ft 3.37 in). Cross-referencing this against a US or UK sizing chart is the fastest way to find your fit without needing to try on the item. Inseams, shoulder widths, and rise measurements all follow the same math.
In a science or math class, you might measure an object as 100 cm using a metric ruler, then need to express it in the imperial system for a comparison exercise or US-format worksheet. The answer is 39.37 inches, or 39 3/8" in fractional form. A useful rule of thumb to remember: 1 inch = 2.54 cm, and 1 cm ≈ 0.394 inches. For 100 cm: 100 × 0.394 ≈ 39.37 in.
