MPH ↔ KM/H Swing Speed Converter

About This Converter

This tool helps golfers convert swing speeds between miles per hour (MPH) and kilometers per hour (KM/H). This is useful when:

• Using launch monitors or swing speed radars with different unit settings
• Comparing swing speed data from different devices or apps
• Understanding club fitting recommendations from international sources
• Following golf instruction that uses different measurement systems
• Comparing your swing speed to professional players worldwide

Average Swing Speeds by Club

Why Swing Speed Matters

Swing speed is one of the most important factors in golf performance:

• Ball Speed: Higher swing speed generally produces higher ball speed and distance
• Club Fitting: Proper shaft flex and weight depend on your swing speed
• Ball Selection: Different compression ratings work better at different swing speeds
• Launch Conditions: Optimal launch angle and spin rate vary with swing speed
• Equipment Matching: Driver loft, iron design, and wedge selection should match your speed

How to Measure Swing Speed

• Launch Monitors: TrackMan, FlightScope, Foresight, etc. provide accurate measurements
• Swing Speed Radars: Portable devices like Swing Caddie, Voice Caddie, SuperSpeed
• Golf Simulator: SkyTrak, Uneekor, GC Quad at indoor facilities
• Pro Shop Fitting: Most golf shops offer free swing speed measurements

Distance Estimation

As a general rule of thumb, driver carry distance in yards is approximately 2.3 to 2.6 times your driver swing speed in MPH:

• 100 mph swing speed ≈ 230-260 yards carry
• 110 mph swing speed ≈ 253-286 yards carry
• 120 mph swing speed ≈ 276-312 yards carry
