I'm trying to figure out how many calories I've burned on a walk.
According to my map, I went 2.39 kms, in 16:23 minutes.
I have NO idea how to do the math.
Any suggestions would be appreciated.

    Thank you! I tried entering all of the information into 'map my walk', and it gave me over 1200 calories burned. I lol'd.

    You couldn't do the math.

    And to see that it probably matches up very closely with a better calculator using your weight (as MFP of course does), and time (as MFP does) and pace, as Pu shows would happen in MFP.
    Use Gross option, which is what MFP, HRM, machine, ect would display.

    8.78 km/hr for this calc. Incline doesn't matter much just walking, unless really steep for a long time.

    Saying I couldn't do the math is an understatement lol.
    Thank you very much for that site, I have book marked it.

    Very few could, fewer yet would want to spend the time trying. Sadly I'm the latter.

    Remember that all of this is an estimate. Don't get too wrapped up in it. Plug it in now, monitor how things go over a few weeks time and if you're not getting the results you planned, tweak your estimates going forward.

    Body weight in pounds * 0.3 * miles walked

    So if you're 200 pounds you get 200 * 0.3 * 2.39/1.6 => ~90 calories

    Ok, please bear with me, I am very easily muddled- what would I log this under here? I can find 'walking' then time per km, but I just can't figure out how long it would take me to walk a km. Math is not my friend. I am working on that too, but it's going to take time.
    Should I just log what the calculator tells me, which is 233 calories?

    I'd actually LOVE to be able to do that math, I just.... can't. I'm working on it.

    No. Use the formula I used above. You can copy-paste the whole thing into Google and it'll even do the math for you - just change the "200" to *your* weight in pounds.

    Remember the number you get.

    When you log in MFP, just pick any walking entry, and play with the minutes until MFP gives you the same number.

    Yeah, I can't figure out which option MFP gives me to use haha.
    messing around with all of them, they are nowhere near what the calculator Heybales linked to is telling me.
    I'm confused, but I refuse to give up.

    It doesn't matter which entry you use because you aren't going to use their result anyway. Use the formula above to get the calorie burn number, then change the "minutes" until MFP gives you the same number.

    That distance at that speed sounds more like a run to me!

    I'm also suspicious of the ap thing I used, I am new to all of this technology stuff.
    It did take me just over 15 minutes according to my house clock, but I'm thinking the distance is off.
    I have rheumatoid arthritis- I can manage a brisk walk at best.

    Ok, I pulled out my paper map, and measured with a ruler. *If* I did this right, I walked just over 1 km, not 2.39?
    I then poked around on google maps, it agrees with my paper and ruler.
    Bah. Why would the app be off by that much? It shows where I walked, and it's correct.
    I'm not really stressing over this, I am losing weight doing what I'm doing, I'd just like to be as accurate as possible, for interest sake.
    It's finally not freezing here, so I can start walking again, feeling safe and not afraid of falling, again, many times, on ice.

    I logged the 90, that seems correct.
    I'm happy with that.

    Ok, I tried another ap, and it said the same thing for distance- twice as far as I actually went.
    Does anyone know of an accurate ap?

    When I want to pre-map a ride or run to confirm I've got enough distance - always found it about right on when I actually do the workout.
    Have also used it when someone who shall remain unnamed forgot to charge the Garmin and it died mid workout, so finished it manually.

    Then this app takes the map and makes a .gpx file out of it for my upload to my workout tracker.

    That's just extra.

    Thanks to you both! I'll check out your recommendations :)

    You can also map the route manually (not via the app or via the automatic mapping option) on the desktop site of map my walk - it is much more accurate that way, provided you know exactly where you went!

    That's what I did for the last two nights :)
    I'm going to try aps on the route that I know the exact distance on, and use the one that's closest for going other places.
    I just got an ithinger, I'm excited to use it!

    For calories I like to use this site: http://www.shapesense.com/fitness-exercise/calculators/walking-calorie-burn-calculator.aspx and put in my numbers. Then I pick any of the walking choices on MFP's cardio section and adjust the calories to meet what the calculator came up with.
