  • We’re not dumb

    I’m not suggesting this at all. I’m arguing that using “parts per 10 million” makes more sense to an American audience because fractions are more common in America. So using non common denominators is easier for an American audience. Whereas in metric countries, using standard denominators like thousand, million, billion, etc with decimals and significant figures is easier to interpret.

    it’s a simple fact that comparing 5 to 20 is easier than comparing 0.05 to 0.2.

    Sure, but you’re ignoring the additional cognitive load of using non common denominators. And losing the ability to easily compare these metrics with others.

    Every engineer and scientist in the US uses metric

    Imperial measurements are commonly used in construction & civil engineering in the US.


  • In metric countries, parts-per notation is common but it’s normally per million, billion, trillion, etc. Parts per 10 million is not common. Using an uncommon parts-per notation makes it difficult to compare between countries for instance as it’s unlikely that other countries are reporting in parts per 10 million.

    The imperial measurement system uses fractions, 3/4 inch, etc. The metric system uses decimals, 19mm, etc.

    So to represent this data in a metric country you would use per million inhabitants and use 2 significant figures. Decimals are easy for people who grew up in metric countries to understand.

    I moved to Canada which used a lot of imperial measurements for building materials and tools (it’s a weird mix). I find the imperial system confusing with its use of fractions but I know lots of people that grew up with this system prefer it.

    That’s why I think this globally uncommon per 10 million inhabitants might feel normal for Americans.










  • What are you hosting and who are your users? Do you receive any legitimate traffic from AWS or other cloud provider IP addresses? There will always be edge cases like people hosting VPN exit nodes on a VPS etc, but if its a tiny portion of your legitimate traffic I would consider blocking all incoming traffic from cloud providers and then whitelisting any that make sense like search engine crawlers if necessary.
