So I've seen Mcal everywhere when talking about equine nutrition, but I don't really know what they are. I emailed Standlee asking how many calories per pound were in their Alfalfa pellets, and they told me 0.90 Mcal. I tried to do the conversion to regular calories on google, but it said 0.90 Mcal was equivalent to 900,000 calories. Clearly I'm missing something here....
