**How many centimeters (cm) are in 1 inch (in)?** **What is the formula for how to convert centimeters to inches (cm to in)?**

**1 centimeter (cm) = 0.39370078740157 inch (in)**

So we can say that there is 0.39370078740157 inch in 1 centimeter.

This means that the multiplication conversion factor to convert a quantity expressed in a centimeter unit of measurement to an equivalent quantity expressed in an inch unit of measurement is 0.39370078740157.

Inversely (or reciprocally),

**1 inch (in) = 2.54 centimeters (cm)**

So we can say that there are 2.54 centimeters in 1 inch.

This means that the division conversion factor to convert a quantity expressed in a centimeter unit of measurement to an equivalent quantity expressed in an inch unit of measurement is 2.54.

Knowing this inverse mathematical relationship between the two conversion factors and their reciprocal operations, we can derive two formulas to calculate and convert a quantity of length expressed in centimeters to an equivalent quantity of length expressed in inches (cm to in). Both formulas will yield the same result. The formulas are:

in = cm × 0.39370078740157→ This is the formula based on the multiplication conversion factor.

and

in = cm ÷ 2.54→ This is the formula based on the division conversion factor.

#### A note on the centimeters to inches formula based on the multiplication conversion factor:

For everyday manual calculations where a high degree of precision is not required, it is acceptable to use the approximation:

**in ≈ cm × 0.4**

Using a multiplication factor of 0.4 provides a rough estimation that is suitable for quick calculations for converting centimeters to inches.

On the other hand, if a precise conversion is necessary, such as in scientific or engineering applications, it is recommended to use the more accurate multiplication factor of 0.39370078740157 to minimize rounding errors and ensure greater accuracy in the conversion from centimeters to inches.

For example, if you have a length of 100 centimeters that you want to convert to inches, you would use either of the two formulas as follows:

in = 100 cm × 0.39370078740157 = 39.370078740157 in

in = 100 cm ÷ 2.54 = 39.370078740157 in

So, the result is the same using either formula, which is 39.370078740157 inches or 39.37 inches when rounded off.
