五寸照片是多少厘米？

当提到照片尺寸时，我们常常会遇到不同的度量单位，如厘米、英寸和毫米。这些单位之间的转换可能会让人感到困惑。在中国，常见的照片尺寸之一是五寸照片，那么它究竟有多少厘米呢？

首先，我们需要知道五寸照片是指照片的对角线长度。五寸是英制单位，等于5英寸。而英寸与厘米之间的转换关系是：1英寸=2.54厘米。因此，五寸照片的对角线长度就是5英寸乘以2.54厘米/英寸，计算结果为12.7厘米。

综上所述，五寸照片的对角线长度为12.7厘米。但需要注意的是，实际的照片尺寸可能会略有变化，因为照片的边框大小和裁剪方式可能会不同。

What is the size of a 5-inch photo in centimeters?

When it comes to photo sizes, we often encounter different units of measurement such as centimeters, inches, and millimeters. Converting between these units can be confusing. In China, one of the common photo sizes is the 5-inch photo. So, how many centimeters is it exactly?

Firstly, we need to know that the 5-inch measurement refers to the diagonal length of the photo. The inch is an imperial unit, and 1 inch is equal to 2.54 centimeters. Therefore, the diagonal length of a 5-inch photo can be calculated by multiplying 5 inches by 2.54 centimeters/inch, which results in 12.7 centimeters.

In conclusion, the diagonal length of a 5-inch photo is 12.7 centimeters. However, it's important to note that the actual photo size may vary slightly due to the size of the photo frame and cropping methods used.
