Haemoglobin and the red cell

The Royal College of Pathologists of Australia say that the mean amount of haemoglobin in each red cell is 27 - 32 pg (picograms) reference - let's say around 30 pg, which is 0.000 000 000 03 grams

A haemoglobin molecule has a molecular weight of around 64 500. This is around 107 zg (zeptograms), or 0.000 000 000 000 000 000 107 grams

Dividing the weight of the haemoglobin in a red cell by the weight of one haemoglobin molecule gives the number of haemoglobin molecules in one red cell, which would be (on average, very approximately) 280 000 000
