RO Arrow Weight Formula:
| From: | To: |
RO (Recurve Olympic) arrow making involves assembling arrows with specific components to achieve optimal performance for recurve archery. The total weight of an arrow is the sum of its individual components' weights.
The calculator uses the RO arrow weight formula:
Where:
Explanation: This simple additive formula calculates the total arrow weight by summing the weights of all individual components.
Details: Accurate arrow weight calculation is crucial for consistent arrow flight, proper bow tuning, and achieving desired penetration and trajectory. The total weight affects arrow speed, kinetic energy, and overall bow performance.
Tips: Enter the weight of each component in grains. All values must be valid (non-negative numbers). Use precise measurements from a grain scale for accurate results.
Q1: Why is arrow weight measured in grains?
A: Grains provide a precise measurement unit for small weights commonly used in archery and ammunition. There are 437.5 grains in one ounce.
Q2: What is a typical total weight for RO arrows?
A: Typical RO arrow weights range from 300-500 grains, depending on draw weight, arrow length, and archer preference.
Q3: How does arrow weight affect performance?
A: Heavier arrows provide more kinetic energy and penetration but fly slower. Lighter arrows fly faster but may be less stable in wind and have less penetration.
Q4: Should all arrows in a set have the same weight?
A: Yes, for consistent performance, all arrows in a set should be weight-matched within ±1 grain.
Q5: How do I measure component weights accurately?
A: Use a precision grain scale that measures to at least 0.1 grain accuracy for best results.
