I am looking at a vaccine product that states the amount of vaccine is a range of 4.0 log to 5.8 log PFU (where PFU is just the unit of measure). How would this look when calculated? And how do I perform this calculation?

The log measure is very common in many areas in science, such as the strength of an earthquake, which is measured on the Richter scale. So, an earthquake that registers 8 on the Richter scale is 10 times stronger than 7 on the same scale. Because 8-7=1, which means 10^1=10x stronger.
5.8-4=1.8, which means 10^1.8=63 times on the common base 10.
But, there is another Log Base, which is called "Natural Log", with the base "e", which is equal to about 2.718281828........, Therefore, if your logs are to the natural base "e", then it would be e^4 or e^5.8. The difference of 1.8 would amount to only e^1.8=~6 times stronger or bigger or more potent...etc.
