Inches to centimetres is fixed by the 1959 international yard agreement: 1 in is exactly 2.54 cm. Multiply inches by 2.54 and you are done — no rounding, no regional variant. The conversion shows up in TV sizes (a 55 in screen has a 139.7 cm diagonal), monitor specs, US recipe measurements borrowed by metric kitchens, and shoe inserts. If your source is decimal inches (3.75 in), convert directly; if it is fractional (3-3/4 in), expand the fraction first.
Parents tracking a baby's growth chart get length measurements from a US paediatrician in inches but the WHO growth percentile charts most apps default to are plotted in centimetres. A 21 in newborn length is 53.3 cm, and plugging the wrong unit into a growth app silently shifts the child's percentile ranking by dozens of points. Always confirm which unit the chart expects before entering a single measurement — the app rarely warns you if you feed it the wrong one.

A US quarter coin is about 1 inch in diameter. A standard sheet of US Letter paper is 8.5 × 11 inches. A 13-inch laptop has a screen diagonal of 13 inches. In centimeters, that gives you: 1 in = 2.54 cm, 10 in = 25.4 cm, 100 in = 254 cm.
The inch (in) is a unit of length in the imperial and US customary systems, defined as exactly 25.4 millimeters since the 1959 international yard and pound agreement. It is the standard unit in the US for screen sizes, lumber, fasteners, and personal height when given in feet-and-inches form. Twelve inches make one foot.
The centimeter (cm) is a metric unit of length equal to one-hundredth of a meter. It is the most common everyday unit outside the US for measuring small to mid-sized objects, body dimensions like height when stated in metric, fabric, and TV diagonals. A US quarter coin is about 2.4 cm wide; an average adult thumb is around 6 cm long.
