One nanometre can be expressed in scientific notation as 1 × 10 −9 m and as ⁠ 1 1 000 000 000⁠ m. The nanometre was formerly known as the " millimicrometre " – or, more commonly, the " millimicron " for short – since it is ⁠ 1 1000 ⁠ of a micrometer.

Just how small is “nano?” In the International System of Units, the prefix "nano" means one-billionth, or 10-9; therefore one nanometer is one-billionth of a meter. It’s difficult to imagine just how small that is, so here are some examples: A sheet of paper is about 100,000 nanometers thick; A strand of human DNA is 2.5 nanometers in ...

2025年1月1日 · A nanometer (nm) is a unit of measurement in the metric system equal to one billionth of a meter (10^-9 meters). To provide context, a single nanometer is roughly 100,000 times smaller than the width of a human hair, which is …

Convert between the units (nm → m) or see the conversion table.

2024年9月27日 · What is the value of 1 nm? One nanometer (nm) is equal to one billionth of a meter, precisely 0.000000001 meters or 10−910−9 meters. It is commonly used to measure atomic and molecular dimensions.

2024年5月21日 · A nanometer is quite small, a billionth of a meter. It is 20 times wider than the diameter of a hydrogen atom. In terms of the electromagnetic spectrum, 1 nanometer is about the wavelength of soft x-rays.

A nanometer is one billionth of a meter. (A meter is 39.37 inches, or slightly longer than one yard.) The prefix “nano” means “one billionth”, or 10 -9 , in the international system for units of weights and measures.

One nanometre (nm) is 10−9 metre. The micrometre (μm), which equals 10−6 metre, is often used to describe infrared radiation.

2022年7月27日 · Convert meters to nanometers (m to nm) by dividing meters by 10-9 or multiplying by 10 9. Alternatively, convert m to by writing the value in meters in scientific notation and adding 9 to the exponent.

2021年7月30日 · A nanometer (nm) is a unit of length in the metric system, equal to one billionth of a meter (1 x 10-9 m). Many have likely heard of it before–it’s frequently associated with nanotechnology and the creation or study of very tiny things.
