Dear convert-me.com forum visitors,
Our forum has been available for many years. In September 2014 we decided to switch it to read-only mode. Month after month we saw less posts with questions and answers from real people and more spam posts. We were spending more and more resources cleaning the spam until there were less them 1 legitimate message per 100 spam posts. Then we decided it's time to stop.
All the posts in the forum will be available and searchable. We understand there are a lot of useful information and we aren't going to remove anything. As for the new questions, you can always ask them on convert-me.com FaceBook page
Thank you for being with us and sorry for any inconveniences this could caused.

The BTU is imprecisely defined because the properties of water change depending on the temperature range over which the properties are measured. It is the heat to heat 1 lb of H2O 1 degree F, but temperature of the water matters, and there are about 10 "flavors" of BTU which differ in 4th significant figure and beyond.
However, 1 IT "steam table" BTU = 1.055056 kJ.
Measured under other conditions, values range from 1.05435 kJ to 1.05967 kJ.
(Similar problems exist with the calorie and Calorie)
