How does one accurately calculate calories in potato? Specifically sweet potato.
They come in soooooooo many different sizes and I don't have a scale.
Looking online I found between small=50-90c medium=100c large=160-280
I had a large sweet potato that was 5.5 inches long and 3-3.5 inches in diameter
On most websites they say 180gr of sweet potato is considered large
180gr I found out doesn't even equal 1/3 pound. I put my potato on the scale I stand on to weigh myself and it said 1.5lb. I have a good scale, but that just doesn't seem right.
I could only have 300c for dinner, so I figured a small yukon gold potato would be 100 and my large sweet potato would be 160-200, equal to my 300
I know all potato dinner isn't ideal, but I had only had green leafy veggies and fruits from earlier.
I used to think sweet potatoes were really high in calories and i avoided them, but I found out that they have a high percentage of water and are surprisingly low.
I'm on a strict diet and exercise program and I am just curious. how do we accurately read calorie info of whole foods without a scale? Thanks!

Personally I am a big fan of food scales and they really are not particularly expensive (and they are useful both for calorie counting and for following recipes).
However you can also use volume measurements.
http://www.nutritiondata.com/facts/vegetables-and-vegetable-products/2667/2
says 1 cup of baked in skin sweet potato is 200g (and gives calories when selecting this in drop-down)
http://www.nutritiondata.com/facts/vegetables-and-vegetable-products/2668/2
says 1 cup of mashed boiled sweet potato is 328g (and gives calories when selecting this in drop-down)
so if you have a measuring cup, or some other way of measuring volume, you can use that. One cup (US) is 237ml if you use metric.

Yes I really want a scale, but I have heard that they can easily be off and I don't have any money to spare. I have wanted one for years, I love to cook and bake.
Yes I know about those cup measurements, I don't like that either because I don't eat the potato mashed. I cut it into cubes and roast in oven without oil and eat like that, if I mash it, it ruins the whole thing for me. I thought about stuffing my cooked cubes into a measuring cup, just haven't done it yet.

I posted two links. The first one I am assuming is for cubed because one cup is only 200g (compared with much more for the mashed which is more tightly packed)
I've used kitchen scales for years and they're quite reliable. For example one of the units I use is to the nearest gram. Compare that with what was available years ago - 10 or so years ago the scales reported to the nearest 5g so a lot less precise.
You should search Amazon or eBay, they're probably not as expensive as you think they are.
