>> Dear Kevin

>> You test the moisture content using a small digital scale, like you get
>> at a "head shop". It will have a capacity of about 400 or 250 grams. It
>> reads to 0.01 g precision.
>>
>> Take some samples of fuel, weigh them and write the number 1, 2, 3 etc on
>> them with a pen and record the individual masses.
>>
>> You can weigh them all at once if you like.
>>
>> Then put them into a warming drawer of an electric over of the oven
>> itself if you can control the temperature down to 105 C.
>>
>> Leave them for a day (no kidding) and weight them again after they cool.
>>
>> Hot fuel can influence the scale's reading.  Physics 101.
>>
>> Divide the new dry mass by the original mass and convert to %. That is
>> the dry portion. Subtract that number from 100% and you have the moisture
>> on a Wet Weight Basis. WWB.
>>
>> WWB is the most common form of describing the fuel moisture in the stove
>> world. However if you are reading something from the USA never assume it is
>> WWB. There is penchant for describing the moisture as a percentage of the
>> dry mass which is of course the Dry Weight Basis.
>>
>> So you should always report the moisture as a % and then put WWB
>> afterwards so anyone reading your text knows what you did.
>>
>> 100% - Dry mass % = % moisture content WWB
