Calculation: Here is the formula for FIP: FIP = ((13*HR)+(3*(BB+HBP))-(2*K))/IP + constant. The constant is solely to bring FIP onto an ERA scale and is generally around 3.10. You can find historical FIP constant values here, or you can derive the constant yourself.
Your doctor can calculate the GFR based on gender, age, body size, and blood creatinine level. The formula used in clinical practice is called the Cockcroft-Gault equation: ...
