Wheel Speed Calculator [ RPM, Vehicle Speed, Gear Ratio ]

To calculate wheel speed, multiply the circumference of the wheel by its revolutions per second (calculated from RPM). This determines the linear speed of the wheel.

The Wheel Speed Calculator simplifies determining a wheel’s rotational speed based on its diameter and revolutions per minute (RPM). It is particularly valuable for automotive enthusiasts, engineers, and bikers who need to account for gear ratios, tire sizes, or speedometer recalibrations.

This tool is adaptable to various applications, including vehicles, grinding machines, and bicycles, offering precision and efficiency.

Formula:

$S = [2 \cdot \pi \cdot (D/2)] \cdot [\text{RPM}/60]$

Variable	Description
$S$	Linear speed (distance/time)
$D$	Diameter of the wheel (in inches)
$\text{RPM}$	Revolutions per minute

Solved Calculations:

Example 1: Bike Wheel Speed

Step	Value	Explanation
Wheel Diameter	$28 \, \text{inches}$	Diameter of the bike wheel
RPM	$200 \, \text{RPM}$	Rotational speed
Circumference	$2 \cdot \pi \cdot (28/2) = 87.92 \, \text{inches}$	Calculate circumference
Linear Speed	$87.92 \cdot (200/60) = 293.07 \, \text{inches/second}$	Multiply by revolutions per second

Example 2: Grinding Wheel Speed

Step	Value	Explanation
Wheel Diameter	$6 \, \text{inches}$	Diameter of the grinding wheel
RPM	$3000 \, \text{RPM}$	Rotational speed
Circumference	$2 \cdot \pi \cdot (6/2) = 18.85 \, \text{inches}$	Calculate circumference
Linear Speed	$18.85 \cdot (3000/60) = 942.25 \, \text{inches/second}$	Multiply by revolutions per second
