“Gazprom in Figures 2011–2015” gives the following definition of British
Thermal Unit (page 91).
1 million BTUs = 0.028 mcm of gas
The same conversion table defines 1 mcm of gas as
1.154 t c.e. (ton of coal equivalent) and puts the calorific value of 1 kg of
c.e. at 29.3076 MJ. Knowing this, we can calculate the value of Russian BTU in
Joules.
1 million (Russian) BTUs =
947 MJ
One million of
standard BTUs
converts to about 1055 MJ.

Figures 2011-2015
Therefore, one "Russian BTU" is not
enough to raise the temperature of one pound of water from 60° to
61°F at a constant pressure of one atmosphere. Gazprom uses smaller
"Russian BTUs" and gets more of them.
P.S. According to the mentioned
calorific value, one thousand cubic meters of gas equals to 32.056
million BTUs.
