? Converting % of phosphorus to mg/100kcal?

[Bronx's dad (GA)]

Hi all, Dr Lisa's chart uses phos mg/100kcal but many cat food companies list phos as a percentage. Anybody know how to convert the #s so I can use Dr Lisa's chart? Thanks!

To convert % phosphorous to mg/100 calories.
- Multiply % phosphorous by the weight of the can contents
- Multiply that by 0.01 to get weight of phosphorous in the can
- Divide that by the calories in the can and then multiply that by 100 to get weight of phosphorus/100 calories
To convert ounces multiply by 28349.5
