British AT gun classification

[Maelstrom]

I've always been a bit unclear on how the Brit 'pounder'guns converted to mm. Anyone want to enlighten me ?

2pounder- between 30-50mm ?
6pounder- ?
17 pounder- 75mm/54 ?

Yeah i was confused too untill i read this funky book on AT weapons (which i cant remember)

note this is from memory so i may be wrong about some of them
2 punder- 37mm
6 punder-57mm
17 punder-76mm
20 punder-81-85mm(cant remember )

2 Pounder = 40mm

Hi Maelstrom, the British designation is the shell weight not the calibre in millimetres, in fact the 13pdr and the 15dr Mk.1 mounted a 76.2mm gun, but if you want to know the “translation” for WWII AT guns:
- QF 2 pdr Mk.VII- 40mm (1.57in)
- QF 6 pdr 7cwt Gun Mk.2- 57mm (2.244in)
- Ordnance OF 17 pdr Gun – 76.2mm (3.0in)
