Clocking Gas Meter Formulas:

Natural Gas BTUs per Cubic Foot = 1000 BTUHR
Liquid Propane Gas BTUs per Cubic Foot = 2516 BTUHR

BTU’s Per Hour (more averaging):

BTUHR=((Dial Revolutions)/(Seconds to do Revolutions))x Dial size x 3600 sec⁡〖hr x Gas Rating BTUs per Cubic Foot〗

Example:
Dial Revolutions: 4
Time to do 4 Revolutions = 60 Seconds
Dial size = 5 Cubic Feet
Seconds per Hour = 3600
Natural Gas = 1000 BTUHR per Cubic Foot

Step 1: BTUHR=((4 Revolutions)/(60 Seconds))x 5CuFt x 3600 sec⁡〖hr x 1000 BTUperCuFt.〗

Step 2:
BTUHR=0.06666666666666666666666666666667 x 5CuFt x 3600 sec⁡〖hr x 1000 BTUperCuFt.〗

Step 3: BTUHR=1,200,000

Another Way to figure out BTUs per hour:

Cubic Feet per Hour of Gas Formula:
.
CFH Cubic Feet of Gas per hour CFH= ((3600 sec⁡hr x Dial Size))/(Time in Seconds for 1 Revolution)

BTUHR if you know Cubic Feet Per Hour of Gas.

BTUHR=CFH x Gas Rating BTUs per Cubic Foot
