Draw Weight (Bow Poundage)Archery & Ballistics
Convert between Pounds (lbs) and Kilograms (kg) draw weights. View recommended setups for various target types.
Formula values are estimated for target shooting, olympic competitive setups, and civilian hunting ballistics profiles. Actual outdoor wind resistance, drag deviations, and atmospheric temperature changes may alter exact values.
Advanced Recurve / Starter Compound
Standard target competition weight. Demands decent shoulder strength.
