The Reference for Lawful Measures of Volume and Weight

Question:
What are the lawful measures of volume and weight? In most days in the countries.

Answer:
The jurists say that measures of volume and weight are referred back to the measure of Makkah and the scale of al-Madinah. What was considered a measure of volume in the custom of the people of Makkah at the time of the revelation of the revelation remains a measure of volume, and what was considered weighed in their custom remains weighed. This is the reference of measures of volume and weight to the custom of the people of Makkah and al-Madinah at the time of the revelation of the revelation. So what they considered a measure of volume is always considered a measure of volume, and what they considered weighed at that time is always considered weighed.
