A pitch speed conversion chart compares ball-flight time across different distances. It does not measure a hitter's personal reaction time. This chart shows the speed, in mph, that would give the same constant-speed flight time over an assumed 55.5-foot reference distance.

For example, 45 mph over 25 feet takes about 0.379 seconds. That equals 99.9 mph over 55.5 feet, rounded to 100 mph in the chart. The number 100 is an equivalent speed—not 100 milliseconds and not proof that a hitter can hit a live 100 mph fastball.

Pitch Speed Conversion Chart: Equivalent MPH at 55.5 Feet

Find the actual ball speed in the left column, then choose the ball's travel distance across the top. Each cell is the equivalent speed over 55.5 feet, rounded to the nearest mph. Distances mean ball travel from release to the same comparison endpoint, not automatically the distance from the pitching rubber.

Scroll inside the chart to see all speeds from 35–90 mph. On smaller screens, scroll sideways for all distances.

Chart clarification, September 14, 2026: The original numeric values are retained. The reference distance is now stated explicitly, and the former 35-foot column is labeled 36 feet to match its calculations. This is a timing comparison, not a recommended pitching-machine setup.

How to Calculate Equivalent Pitch Speed and Flight Time

You need three inputs: actual speed, actual travel distance, and the reference distance you want to compare. Keep both distances in the same units.

Equivalent speed (mph) = actual speed (mph) × reference distance (ft) ÷ actual travel distance (ft)

Flight time (seconds) = 15 × travel distance (ft) ÷ [22 × speed (mph)]

The time formula converts mph to feet per second using 1 mile = 5,280 feet and 1 hour = 3,600 seconds. It assumes the ball travels at a constant speed; it does not model slowing during flight.

Worked example: 45 mph from 25 feet

Flight time: 15 × 25 ÷ (22 × 45) = 0.3788 seconds, or about 379 milliseconds.
Chart equivalent: 45 × 55.5 ÷ 25 = 99.9 mph, rounded to 100 mph.
Different reference: Using 60.5 feet instead gives 45 × 60.5 ÷ 25 = 108.9 mph for the same modeled flight time.

This is why two charts can report different equivalents for the same practice setup: they may use different comparison distances. Always check the reference before comparing their numbers.

Why This Chart Uses 55.5 Feet, Not Automatically 60 Feet 6 Inches

The 55.5-foot reference reproduces this chart's original calculations. It is an assumed comparison flight distance, not a universal release point or a regulation pitching distance.

MLB's rubber is 60 feet 6 inches from home plate; release occurs closer. See MLB's explanation of pitcher extension.

Use a consistent endpoint for both the practice and reference distances. If the machine or pitcher releases the ball in front of your distance marker, the ball's actual flight distance is shorter than that marked distance. A change in distance changes the calculated equivalent.

Ball-Flight Time Is Not the Same as Hitting Reaction Time

The chart models how long a ball travels. It does not measure when a hitter recognizes a pitch, decides whether to swing, starts moving the bat or reaches contact.

A machine-fed ball and a live pitch may have similar flight times but different release cues, movement, location and predictability. Matching flight time alone does not recreate every demand of an at-bat. Nor does it establish the level of competition a hitter is ready to face.

For a useful practice record, keep the measured speed, release-to-endpoint distance, equipment setup and task consistent. Record contact quality and swing decisions separately; an equivalent-mph number cannot substitute for those observations.

How Coaches and Players Can Use the Chart

Measure the setup. Record the ball speed and the distance it actually travels. Do not mix a machine's position with its release point.
Select the reference. Use 55.5 feet for this table. For another reference, use the formula rather than relabeling the existing values.
Separate timing from performance. Treat equivalent mph as a timing comparison, not a measured reaction score, radar reading or predicted hitting result.
Keep training decisions separate. Follow equipment instructions and qualified supervision. The chart is not a recommendation to move a machine closer or increase speed.

Trying to calculate a pitcher's measured speed instead? Read the pitching velocity calculator guide for the distinction between measured velocity, distance/time calculations and predicted potential.

Pitch Speed Conversion Chart: Common Questions

What does 100 mean when the chart shows 45 mph at 25 feet?

It means approximately 100 mph over this chart's 55.5-foot reference distance would produce the same constant-speed flight time. The modeled time is about 0.379 seconds. It does not mean a reaction time of 100 milliseconds.

Does hitting that pitch mean I can hit a real 100 mph fastball?

No. The chart equates flight time only. It does not account for a live pitcher's delivery, pitch recognition, movement, location or the hitter's swing decisions.

Why is one distance column 36 feet instead of 35 feet?

The original values in that column calculate correctly at 36 feet with a 55.5-foot reference. The heading has been corrected while retaining the numeric values. For 35 feet, calculate actual mph × 55.5 ÷ 35.

Can I use this chart for a different field distance?

Use the formula with your chosen reference flight distance. Do not treat 55.5 feet as the required reference for every age, field or pitcher. Identify release and endpoint consistently, and keep the chart separate from equipment and training-safety decisions.

Hi,
I have a question. My 12 year old can hit a 45 mph pitch consistently from 25 feet. We use the conversion chart for the reaction time. It gives the reaction time as 100. He is using a BBCOR 30 oz. drop 3 bat. Anything in the 35-38 range he completely smokes and he pulls anything under 45. Am I understanding the chart correctly? We go to his team practices and he’s so far ahead of the pitches from other kids. Is this a normal thing?
Thanks,
Joe
