تحویلِ اکائیات اصل میں ایک ہی مقدار کے لیے مختلف پیمائشی اکائیوں کے جز و ضربی (factor) کی تبدیلی ہے۔
مختلف اکائیوں میں کسی مقدار کی قیمت معلوم کرنے کے لیے تحویلِ اکائیات کا عمل استعمال کیا جاتا ہے۔

Often, information entropy is measured in shannons, whereas the (discrete) storage space of digital devices is measured in bits. Thus, uncompressed redundant data occupy more than one bit of storage per shannon of information entropy. The multiples of a bit listed above are usually used with this meaning. Other times the bit is used as a measure of information entropy and is thus a synonym of shannon.
