Which is steeper 10 or 20

Which method of displaying gradients do you prefer? Ratios e. Post by mittfh » Fri Apr 27, After voting in the PotM poll, it caught me thinking as to which method of describing gradients you prefer: Old-style ratios: , , , , , , , For every unit of measurement you go up vertically, you travel x units horizontally.

Hence the steeper the hill, the lower the second number. Post by haymansafc » Fri Apr 27, I don't really have a preference when it comes to the signing of gradients.

I can happily accept both signs although I will understand if the old style ratios will come out on top considering they have been used longer and no doubt more people will understand them.

I understand both well although I will admit when I see a percentage sign, I have a habit of converting it back to the old measurement in my mind! As a side note, when it comes to distance on signs though - I'd have miles any day over unfathomable km.

Just thought I'd add that! Post by Ian » Fri Apr 27, If there was an option for "neither - use another scheme" I'd have picked it, as I like the idea of gradient in degrees. Using sine, there's a reasonable point scale, e. Lest we forget Post by M45 Tailback » Fri Apr 27, I much prefer the older ones because I can 'visualize' a or hill.

Click to see full answer. It expresses the ratio of difference in altitude between two points on a slope to the horizontal distance between the points, multiplied by Different symbol different meaning. Degrees Gradient Percent 7. Calculating a Slope Gradient Both numbers must use the same units. For instance, if you travel 3 inches vertically and 3 feet 36 inches horizontally, the slope would be or This is read as a "one in twelve slope.

Twelfth grade, senior year, or grade 12 is the final year of secondary school in most of North America. In other regions it is also equivalently referred to as class 12 or Year Twelfth grade is typically the last year of high school; graduation year. How do you determine slope? The slope of a line characterizes the direction of a line. To find the slope, you divide the difference of the y-coordinates of 2 points on a line by the difference of the x-coordinates of those same 2 points.

If the road is climbing then this means for every units you travel horizontally you increase your altitude by 6 units. There are many slope style bikes out there, it may be in the local shops or online. Always choose the best and quality bikes like Trek, Giant, Morpheus Bikes and others. I just asked a dumb question.

The distance is converted to metres meters for the calculations. This example uses metric measures kilometers and meters. Are all published gradients calculated with metric units? Thank you so much! Wonderful Explanation without being bogged down with science and maths. It was comfortable for me but best bit was Flying back down the twisty road, wonderful. Interesting Observations throughout. Thanks for whoever put this together. Try Lincoln Gap toughest mile in America.

A four mile hill. It was the hardest thing I have ever done on a bike. Far far simpler if one sticks to something sensible such as ratios for hills. Damn straight Robbie! The entire rest of the world IS ridiculous!

Ridiculous percentage system? Is it linear? Billy, no, it is not a linear relationship. However this took me nearly two years to get there by riding Kms a week and constantly challenging myself on the many steep climbs in the Dandenongs. I am afraid the only answer is hard work. Good luck with your project as it will be worth it in the end. Climbing hills on a bike is not hard. It depends how fast you want to go and your gearing. If you have the right gearing, climbing can be as comfortable as riding along the flat.

The problem is psychological. We all watch Le Tour too much! Thank you so much… I and my students found this to be very useful and helpful when studying gradient percentages in geography. Thank you! Nice to know that good ole Pythagoras is relevant to sports people!!! Great article about gradients. My second question is about training.

Hey Matt, will you be looking at the road condition as part of this? Sure will mate. Stay posted. Is it the Waterworks climb that we did for H10K that was super rough? You read my mind! I get the average gradient to be 7. Is it average power or RMS power or what? The simple example of a split gradient for a 1km climb is probably in reality 2 climbs one after the other, 2 different gradients.
