How to create re-usable measure?

Hi,

Please help.

I am creating a number of measures for a table and would like to extend the same measures to few more tables with similar info. How to create a reusable measure that can be generically use in other tables?

For example

Table name = "Apple-Table" with below info

Create a measure to calculate the cost as below:

Assume there is another table called "Banana-Table", how to reuse the above measure to this table?

Thanks in advance.
