What is the unit used to indicate speed in the Mitsubishi A6M2-21 (same until A6M5c)?
<LI> MPH?
<LI> KNOTS?
<LI> KPH?

According to Pelican's Perch article about flying a restored Zero, this gauge is graduated in knots. Schiffer's book on Japanese planes equipment seems to agree with this (Navy planes indicators - knots, Army planes indicators - kilometers per hour)

Yeah Japanese planes dials can be a bit of a mystery - Knots for IJN and kmh for IJA?Anyway a right pain when trying to level bomb in the Betty in a full real server.

According to our current knowledge this should be the conversion to KMH:

I presume it was more comfortable for pilots this way. If you're a navy pilot, you're happy to use the same unit for your navigation calculations - speed of your carrier, speed of ships you're supposed to find and destroy, speed of wind, speed of your aircraft - all in knots, not additional conversions needed! Army pilot on the other hand will prefer the units all other land rats are used to http://forums.ubi.com/groupee_common/emoticons/icon_biggrin.gif.

Just for the sake of discussion...what did the "J2M Raiden" have on its speed gauge? The J2M was a land based interceptor. Did it have km or knots?

J2M Raiden
Good question! Within 4 days of searching i have found a lot of resource online. It seems like J2M used knots, just as all NAVY planes.

It seems G4M-"Bettys" and D3A1 were using KMH instead of KNOTS...

Hmm, Interesting. I wonder if that was because most navy fighter pilots where used to gauging speed in knots?

Using knots has distinct advantages in navigation.
