If you’re reading the datasheet for a MEMS barometric pressure sensor, do you really need an equation to tell you that dividing by 4 and multiplying by 0.25 are equivalent? Apparently some technical writer thinks this needs to be explained…

The datasheet then goes on to indicate that dividing a temperature value by 20 is the same as multiplying it by 0.05. Darn, this math stuff is tricky…
