One list of the weights of commodities and agricultural products gives the weight of a cubic foot of spuds at 43 pounds. At that rate (because there are 3 x 3 x 3 = 27 cubic feet in a cubic yard), there are 1161 pounds of potatoes in a cubic yard of the product. Call it a bit over half a ton (US), and you're good to go. The sizes and shapes of the potatoes will vary, and this can (will) affect the overall weight of that cubic yard of them. This is a problem in packing, where variability in size and shape can (and does) occur. One way to see it is this way. Take a cubic foot of river rocks about the size of Golf balls. Take those same rocks and crush them to sand, and they'll take up less space (less volume). It's the exact same material, and the exact same amount of material, but in a more finely divided (and therefore more closely packed) form.
The Russets I buy are about 2" diameter and 4" long, and they weigh about 12 ounces - about 265 calories before I add butter. When you bake a potato, water is steamed off, but that doesn't change the calorie count or the nutrition. Mama always baked potatoes at 375 for an hour or 450 for 45 minutes, depending on whatever else was in the oven, but I bake them at 450 for 60 to 90 minutes. The longer you bake them, the crustier they get, and I like crusty baked potatoes.
1 cubic yard of what?
What is the weight of one cubic yard of cement? If you are asking the weight of 1 cubic yard of CONCRETE it is approximately 2 tons or 4000 pounds per cubic yard when wet.

The answer cannot be known without knowing the substance you are talking about. Kilograms is weight, and cubic yards is volume. A cubic yard of gold is going to weigh more kilograms than a cubic yard of hay.
