miles per hour (mph)
Note: This assumes straight-line travel with constant average speed from release to target. Real shots may vary due to drag and arrow drop.
How it Works
Formula: speed = distance ÷ time
- Distance — the line-of-sight distance to the target.
- Time — measured with a timer or from slow-motion / sound on video.
Unit handling: we convert your distance to meters, your time to seconds, compute m/s, then derive other units (fps, km/h, mph).
Quick Example
At 20 yards with a measured flight time of 0.60 s:
distance = 20 yd = 60 ft → speed ≈ 60 / 0.60 = 100 fps
Tips for Accurate Timing
- Record at high frame rate (120–240 fps) and count frames between release and impact.
- Or use the audio waveform to measure from bow release sound to impact sound.
- Measure distance precisely; small errors can shift results significantly.
Arrow Speed Calculator – Introduction
The Arrow Speed Calculator is a simple yet powerful tool designed for archers, bowhunters, and anyone curious about arrow performance. By entering the distance to your target and the time of flight, the calculator instantly provides the average speed of your arrow in multiple units, including feet per second (fps), meters per second (m/s), kilometers per hour (km/h), and miles per hour (mph).
This tool is especially useful if you don’t own a chronograph. With just a stopwatch, high-speed video, or even audio timing, you can estimate how fast your arrows are flying. Understanding your arrow speed helps in fine-tuning your bow setup, predicting trajectory, and improving shooting accuracy.
How It Works
The calculation is based on the simple physics formula:
Speed = Distance ÷ Time
-
Measure the distance from the bow to the target (in yards, feet, or meters).
-
Measure the flight time of the arrow using a timer, slow-motion video, or sound recording.
-
Enter these values, and the calculator will instantly convert and display the results in all major speed units.
Why Use This Calculator?
-
Archery Practice – check if your arrows are consistent across different shots.
-
Bow Tuning – ensure your bow setup delivers the desired speed.
-
Hunting Preparation – understand your arrow’s flight to improve accuracy at various distances.
-
Learning & Fun – great for students and archery enthusiasts who want to connect physics with real-world archery.
