To convert 54 inches to centimeters, we use the conversion factor where 1 inch is equal to 2.54 centimeters. This conversion factor is based on the definition of the inch in terms of the meter, which is the base unit of length in the International System of Units (SI). Given this, the calculation for converting 54 inches into centimeters involves multiplying 54 by 2.54.
Calculation Process
The calculation is straightforward: 54 inches * 2.54 cm/inch = 137.16 cm. This means that 54 inches is equivalent to 137.16 centimeters. It’s worth noting that for most practical purposes, rounding to two decimal places is sufficient, but in situations requiring higher precision, more decimal places might be necessary.
Understanding the Conversion Factor
The reason we use 2.54 cm as the conversion factor from inches to centimeters is due to the historical definition of the inch and its relationship to the meter. Originally, the inch was defined in terms of the length of a barleycorn, but it was later standardized in terms of the meter. Since 1 meter equals 100 centimeters, and there are 39.37 inches in a meter, dividing 100 cm by 39.37 inches gives us the conversion factor of approximately 2.54 cm/inch.
| Unit | Conversion Factor | Result |
|---|---|---|
| 54 inches | 2.54 cm/inch | 137.16 cm |
