Globe Walkers have been asking for a Step Conversion Chart for activities. You can find one here: conversion_chart.
Find your chosen activity and the chart will tell you how many steps you should count for each minute of that activity – just multiply by the number of minutes you do the activity.
For example bowling is listed as 71 steps per minute. If I bowl for 1/2 an hour I would calculate 71 x 30 (min) = 2130 steps or just over 1 mile.
Pickleball, which is not on the list is considered to be 166 steps per minute.
