The word "poundages" is a relatively uncommon term that refers to weights or measures expressed in pounds. However, there are several synonymous terms that can be used instead of "poundages" depending on the context. For instance, "weight," "mass," and "heft" all refer to the measure of how heavy something is. "Scale," "balance," and "measurement" can be used in cases where the weight or poundage of an object needs to be determined. Moreover, "load" and "burden" may be more appropriate in contexts where the focus is on carrying or lifting heavy things. Therefore, it's essential to consider the context when choosing an appropriate term synonym for "poundages".
