Here's the thing: ".87" by itself doesn't represent a measurement. It could be:
* 0.87 of an inch: This would be a fraction of an inch, less than a full inch.
* 0.87 of a foot: This would be a fraction of a foot, equal to 10.44 inches (0.87 x 12).
* 0.87 of something else: You need to know what the ".87" represents to convert it to inches.
To convert a decimal value to inches, you need to know what the decimal is representing (e.g., a fraction of an inch, a fraction of a foot, etc.).
Please provide more context about what ".87" refers to.
