"Conveniencia" se puede traducir de distintas maneras dependiendo del contexto. Aquí puedes ver distintos ejemplos: http://es.bab.la/diccionario/espanol-ingles/conveniencia

In reality, a better translation would usually be "suitability," not "convenience." Even though English and Spanish are related, some context would allow for a better interpretation.

It means convenience in English.

Thank you!

It is something that is good or useful for a person. For example, you can have a "matrimonio por conveniencia" (marriage of convenience), which means that you'll have benefits product of that marriage. Another example could involve you and a friend talking about an oncoming Chemistry exam. After a few minutes you say: "Me convendría estudiar". This means that you should study, for you are not doing very well in that subject, and if you do (study) it would represent a benefit. I hope this helps! :)
