6.4.7. K factors (in pulse/l) of the fusion spigots and welding sockets with radius for
measuring devices with a g2'' nut
When	the	dimensions	of	the	pipe	are	slightly	different	from	dimensions	d	and	s	given	in	the	table,	recalculate	the	K	factor	using	one	of	
the	formulae	in	chap.	6.4.2.
If	the	measuring	device	does	not	automatically	convert	the	K	factor,	use	the	following	conversion	formulae	before	setting	the	para-
meters	of	the	device:
•	 K	factor	in	pulse/US	gallon	=	K	factor	in	pulse/litre	x	3.785
•	 K	factor	in	pulse/UK	gallon	=	K	factor	in	pulse/litre	x	4.546
