Confused about feeler gauges and inch/metric conversions

The shop manual says "Intake: 0.21 - 0.25 mm(0.008 - 0.010 in.)"

0.008" converts to 0.203mm (which isn't quite 0.21mm), and as such most feeler gauges I find say 0.008"/0.20mm.

Wouldn't 0.20mm be too tight and cause problems?

The next step up that I find is 0.229mm which converts to 0.009". Should this be the go to instead of 0.008"?

How much of a difference would 0.23mm and 0.21mm make in the real world?

I haven't found a 0.21mm feeler gauge anywhere so I'm not sure if it exists as a consumer product.
