Softball to Baseball Pitch Speed Calculator

Softball to Baseball Pitch Speed Converter

Standard: 43 ft

Standard: 60.5 ft

Calculation Results:

Equivalent Baseball Pitch Speed: 0 MPH

Reaction Time: 0 seconds

This means a MPH softball pitch from feet gives the batter the same reaction time as a MPH baseball pitch from feet.

Understanding the Speed Difference: Softball vs. Baseball

In the world of diamond sports, speed is often debated. While a baseball pitch might hit triple digits on the radar gun, softball fans know that 70 MPH in fastpitch is a completely different beast. The secret lies in Reaction Time. This calculator translates the perception of speed based on the shorter distance from the pitcher's rubber to home plate in softball.

The Science of Reaction Time

Reaction time is the total seconds a batter has to decide whether to swing and then physically move the bat. Because a softball pitcher stands much closer (43 feet) than a baseball pitcher (60.5 feet), the ball reaches the plate much faster, even at lower velocities.

To calculate the baseball equivalent, we use the formula for time-of-flight. If the reaction time is the same, the relationship is:

Equivalent Speed = Softball Speed × (Baseball Distance ÷ Softball Distance)

Common Conversion Benchmarks

Softball Speed (MPH)	Baseball Equivalent (MPH)	Reaction Time
60 MPH	84.4 MPH	~0.48 sec
65 MPH	91.4 MPH	~0.45 sec
70 MPH	98.5 MPH	~0.41 sec
75 MPH	105.5 MPH	~0.39 sec

Why Distance Matters

In NCAA Division I Softball, the pitching distance is 43 feet. In Major League Baseball, it is 60 feet 6 inches. However, the release point also matters. Pitchers usually release the ball several feet in front of the rubber. For the most accurate calculation, you can adjust the distance inputs in our tool to account for the actual release point (e.g., using 37 feet for softball and 55 feet for baseball).
