What’s the reason for eggs to be sold in dozen
In: Other
Many things are packaged in 12s because it’s easy to break into different smaller sizes. You could buy 12 eggs, or your could buy 1/2 of that – 6, or 1/4 of that – 3. The seller just cuts the package and hands you the portion.
This is also why you’ll find the number 60 and 360 used. 60 is 3x4x5 and 360 is 3x4x5x6. Easy to divide into smaller portions, which is important not just for goods like eggs and buns, but also math when you have to divide before fractions were invented.
This is likely why we have 12 hours, 60 minutes, 60 seconds and 360 degrees in a circle.
Fun fact – the Babylonian number system was base 60, not base 10. They likely counted to 12 on their hand by tapping your thumb on each segment of your fingers – 3 segments on 4 fingers is 12. Count 5 fingers on your other hand for each 12 and you get 60. It’s the Babylonians who gave us our system of time.
