In other words, 807 nanograms is 0.014 times the weight of a Grain of Salt, and the weight of a Grain of Salt is 72.5 times that amount.The mass of a grain of salt is approximately 58,500 nanograms. Salt consumption varies widely by country; the people of the United States consume a combined total of about 57,000,000,000,000,000,000.0000000000000000000000 nanograms of salt each year.
It's about one-three-hundred-fiftieth as heavy as a Poppy Seed
In other words, 807 nanograms is 0.003 times the weight of a Poppy Seed, and the weight of a Poppy Seed is 370 times that amount.(Papaver somniferum)
Fifty percent oil by weight, a poppy seed weighs approximately 300,000 nanograms. The true pigment of a poppy seed is brown in color, while the characteristic bluish color is an optical illusion caused by a layer of calcium oxalate crystals refracting light rays.
It's about one-eight-hundredth as heavy as a Grain of Sugar
In other words, 807 nanograms is 0.0013 times the weight of a Grain of Sugar, and the weight of a Grain of Sugar is 775 times that amount.(a.k.a. white sugar, a.k.a. white refined sugar, a.k.a. table sugar, a.k.a. sucrose, a.k.a. saccharose)
A grain of sugar weighs approximately 625,000 nanograms. Sugar consumption varies widely by country; the average citizen of the United States consumes about 61,200,000,000,000 nanograms of sugar each year.
It's about one-four-thousand-five-hundredth as heavy as a Sesame Seed
In other words, 807 nanograms is 0.00022 times the weight of a Sesame Seed, and the weight of a Sesame Seed is 4,500 times that amount.(Sesamum indicum)
A sesame seed weighs approximately 3,640,000 nanograms. The McDonald's Big Mac sandwich, which is well-known for its sesame seed top bun, accounts for the consumption of an estimated 2,010,000,000,000,000.0000000000000000000 nanograms of sesame seeds each day.
It's about one-five-thousand-five-hundredth as heavy as a Grain of Sand
In other words, 807 nanograms is 0.0002 times the weight of a Grain of Sand, and the weight of a Grain of Sand is 5,600 times that amount.(medium grain)
With tremendous variety in the size of grain and the component material, grains of sand weigh an average of 4,400,000 nanograms. In 2007, a team of seven in Myrtle Beach created the world's tallest sandcastle, which measured 15.10 m (49.55 ft) in height.
It's about one-twenty-five-thousandth as heavy as a Grain of Rice
In other words, 807 nanograms is 0.000038 times the weight of a Grain of Rice, and the weight of a Grain of Rice is 26,000 times that amount.(conventional; US; long-, medium-, and short-gran varieties; uncooked)
With great differences in variety, the average among a sampling of common short-, medium- and long-grain rices finds that a single grain weighs about 21,000,000 nanograms before cooking. A staple through most of human history, archaeological evidence indicates that the earliest rice cultivation was about 11,500 years ago.
It's about one-two-hundred-fifty-thousandth as heavy as a Raindrop
In other words, 807 nanograms is 0.0000040 times the weight of a Raindrop, and the weight of a Raindrop is 300,000 times that amount.(a.k.a. drop, a.k.a. droplet) (average)
The weight of a raindrop depends heavily on the type of weather, but averages about 200,000,000 nanograms. The familiar teardrop shape of a raindrop is actually an optical illusion, caused by the reflection of the light and the motion of the drop.
