The way you measure nanotechnology is in nanometers, and one nanometer is a billionth of a meter, and to put some scale to that, if you had a nanoparticle that was one nanometer thick, and you put it side by side, and you had 50,000 of them, you'd be the width of a human hair.
나노 기술을 측정할 때는 나노미터 단위를 사용하는데, 1 나노미터는 1미터의 10억 분의 일이고, 길이를 측정하기 위해 1 나노미터 두께의 나노 입자를 나란히 놓아 오만 개를 나열하면 인간 머리 카락의 두께 정도가 됩니다.
