I normally use gb.mapometer.com</p> <p>Average gradient (in percent) is just 100*(change in elevation/distance). </p> Darkerside on "How do you work out gradient?" http://citycyclingedinburgh.info/bbpress/topic.php?id=17832#post-252970 Thu, 15 Jun 2017 12:55:20 +0000 Darkerside 252970@http://citycyclingedinburgh.info/bbpress/ <p>(That's only going to work if the slope is relatively consistent and could be approximated by the hypotenuse of a right-angled triangle. If not you'll have to work out horizontal distance travelled, and use inverse tan instead. Or the Strava thing.</p> <p>Probably the Strava thing...) </p> Darkerside on "How do you work out gradient?" http://citycyclingedinburgh.info/bbpress/topic.php?id=17832#post-252969 Thu, 15 Jun 2017 12:53:08 +0000 Darkerside 252969@http://citycyclingedinburgh.info/bbpress/ <p>I'm assuming the answer you want isn't:</p> <p>[gradient]=sin^(-1)([change in height]/[distance travelled])</p> <p>? </p> jonty on "How do you work out gradient?" http://citycyclingedinburgh.info/bbpress/topic.php?id=17832#post-252968 Thu, 15 Jun 2017 12:52:55 +0000 jonty 252968@http://citycyclingedinburgh.info/bbpress/ <p>Strava has a cool route builder tool (Dashboard &gt; My Routes) which can help you out with this if you don't already have a cycle along the route recorded. </p> <p>Dragging the suggested Google Maps route to resemble what you actually do can also give a rough but less detailed idea of climbs involved. </p> SRD on "How do you work out gradient?" http://citycyclingedinburgh.info/bbpress/topic.php?id=17832#post-252967 Thu, 15 Jun 2017 12:29:31 +0000 SRD 252967@http://citycyclingedinburgh.info/bbpress/ <p>So, if Kaimes Hill is 9%, how do we work out our school run? how does the length to elevation thing work? (or does strava do it automatically for you?) </p>
