For some this might be a silly question but I have come across meters that don't display the KW or MJ rating. I know there is an equation to work out the KW from Cubic meters, can anyone help?

hi guys, don`t know if this conversion chart will help,cheers

42 mj per cub metre ( nat gas ) , to get actual value thru meter multiply 101.5 (atmospheric pressure ) plus regulator pressure x 101.5   this is called meter factor , the retailer mutiplies the cubic meters consumed times the meter factor to get the true amount of gas used ,

Hope this makes sense ,

Going to be interesting how the retailer will charge when they dont have access to gas certificates showing working pressure , I believe they accessed these to determine the meter factor for their customers . It appears all the domestic regulators are standard set at 2.5kpa around wellington area now .

Had an installation recently with 7.5 kpa , bit of a cockup from the meter installer , it was only discovered because we installed a new gas heater , the neigbours were wondering if I was there to look for a gas leak , they had two rinnai infinities discharging towards there backyard , they never complained to anyone though , when we had the reg changed the gas smell went away.and the pilot light on the gas fire in the place stopped flaring like the Maui burn off chimney , this was operating like this for 2 years , I was able to check back online to see who had done the install , that option will soon be gone , I dont understand why they want to remove the online certs , in my opinion it will be a bad move , will have to wait and see   

In my previous post I assumed we were talking natural gas , the chart does make sense with lpg

96 mj per cubic metre

its getting late I should be asleep

Thanks for your help guys, great place to go to with things like this! Cheers
