1. What is a Lean Meat Ratio Calculator?

Definition: This calculator determines the percentage of lean meat in a cut of meat based on the mass of lean meat versus total mass.

Purpose: It helps cooks, nutritionists, and health-conscious individuals understand the composition of their meat selections.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( R \) — Lean meat ratio (percentage)
• \( M_l \) — Mass of lean meat (kg)
• \( M \) — Total mass of meat including fat (kg)

Explanation: The lean meat mass is divided by total meat mass and multiplied by 100 to get a percentage.

3. Importance of Lean Meat Ratio

Details: Knowing the lean meat percentage helps with nutritional planning, recipe adjustments, and making healthier food choices.

4. Using the Calculator

Tips: Enter the mass of just the lean portions and the total mass including fat. Both values must be > 0 and lean mass cannot exceed total mass.
