Do people realize that computers don't count by tens? So should we switch to binary or hex? No! Computer geeks can count hex and the rest of humanity can count by tens.

Consider all the changes in language and the cost for our culture to to adopt metric. Wgen a recipe calls for a cup of water what is the metric replacement? When I want an 8 ft board what is the metric replacement?

Science and engineering can use metric and our culture can use English. That is diversity that keeps everyone happy.
