Pounders - mm help.

Okay, I don't know what a 2 pounder is actually in mm. A 6 pounder is 57 mm, I got that from the mythbuster on the Tiger I. I just want a guide for the British pounders. Basically, list the pounders, and their mm measurement.

 

2 Pounder: 40mm.

3 Pounder: 47mm (I think. I'm sure Tony W will correct me)

6 Pounder: 57mm.

17 Pounder: 76.2mm.

25 Pounder: 87.6mm.

32 Pounder: 94mm ( I think).

60 Pounder: 127mm.

Edited to reflect Christian's post.

 

17 pdr. is actually 76.2 mm. (3 in.)

 

Thanks Chris'

 

And the 20 pounder at 83.4mm, the Brits went metric after that.

 

Now there's an odd measurement if there ever was one.

 

S'pose we ought to include the 18Pdr as well. But I don't know the diameter!

 

84 mm (3.3 inches) according to this source

 

I didn't even know that the 20 Pdr was used in WWII!

 

Thanks guys.

 

It wasn't - it entered service in the Centurion III in 1948.

There were also the 1 pdr and 1½ pdr, both of 37mm calibre.

And it's worth pointing out that in WW1 there were 13 pdr and 15 pdr guns which were both 76.2mm calibre. There was also a 60 pdr of 5 inch (127mm) calibre and a 30 pdr (4 inches/102mm).

the 2pdr was actually only 37mm

 

Nope - it was 40mm.

i'm sure there was 37mm versions because the humber mk 1 armoured car had a 2pdr gun but it was 37mm

 

It was a 37mm, but it wasn't the 2 pdr. See: http://en.wikipedia.org/wiki/Humber_Armoured_Car

General Grevious.

The Bofors anti tank gun, used by the British due to the shortage of 2 Pdrs after Dunkirk, was 37mm.

 

Not to be confused with the Bofors AA gun which was 40mm.

 

thanks for the correction
