Indeed – for example, 100 mmHg = 53.5776 inches of water. Years ago, I used a 6 foot water column to calibrate pressure sensors in the human physiologic range. Needless to say I didn’t want to fool around with mercury. And a water column is a primary calibration, while an aneroid manometer is a secondary one, whose accuracy has to be assumed.

And if it does China can always steal those state secrets as they usually do, and if successful it saves them the R&D.
