Gas rates on lpg system?

[Illuminate]

Can somebody tell me how to gas rate on a lpg system longhand on a metric meter?

On a condensing boiler open hot tap so boiler operates at max

Two minutes test

2nd meter reading - 1st meter reading

X 30 = m3/hr? Correct?

Then converting this to kw net?

M3/hr x propane calorific value 95
Then devide that by 3.6 = kw gross ÷ devide by 1.11 to get kw net?

Can some let me know the correct way with lpg?
