Actually... there are many words for "pesos" (plural of "peso") in English, one of them would be "scale weight" [https://dle.rae.es/?id=Sndl9iL]:
- m. peso que se necesita para equilibrar en la balanza un cuerpo determinado.
In any case, in this context... it is a set of monetary units from different Latin American countries:
- m. Unidad monetaria de la Argentina, Chile, Colombia, Cuba, Filipinas, México, República Dominicana y Uruguay.
These different and unrelated monetary units are also referred as "Pesos" in English.
