hallo, I would like to ask whether is possible to do a macro

the argument is that I have a long text in word 2013, with several length, weight and surface measurements inside (e.g.: 30 meters, 50 tons, 24.5 square meters).

So, I need to find a way to add in the text, concurrently, after these numbers and specific measurement type another number which is the related chinese measuremente

for example:

30 meters, to become in the text after the 'operation': 30 meters (990 jou) - that is the result of 960 is given multipling 30 meters for 32

145 tons, to become in the text after the 'operation': 145 tons (239,751.7 jin) - that is the result of 239,751.7 is given multipling 145 tons for 1653.46

23,000 square meters, to become in the text after the 'operation': 23,000 square meters (34.5 mu) - that is the result of 34.5 is given multipling 23,000 square meters for 0.0015

Of course the automatic operation should be done only by presence of the related words meters, tons, square meters after the numbers, and not with every number in the text

Is that possible to do in word 2013? let me save time and energy

Thanks again for your reply
