‘半斤八两’用英语怎么说？

as broad as it is long:
字面意思看来，这个短语是说“长和宽一样”，稍微引申一点，可以理解为“没有区别，半斤八两”。
它用来表示供选择的两件事物优劣相等，数量相当，与汉语成语“铢两悉称”、“旗鼓相当”的语义比较接近。

Example：
Since both jobs pay 100yuan an hour and are equally boring, it is about as broad as it is long whether I take one or the other.
既然两个工作都是100块一个小时，而且又同样都很无聊，我觉得选哪个都一样，半斤八两
