You can buy these with a calibration certificate for like $70, but I skipped the cert. Should be the same quality, cost me $16. I chose the version with the superior units of measurement.

Not that uncommon. In Canada you can buy metric, imperial, or dual-unit tapes. People who use them routinely at work will buy single-unit tapes so they don’t have to check which side they’re on. Dual units are handy for us mortals who use them infrequently and need both.
