納米（SI符號：nm）是公制系統中的長度單位，等於一米（0.000000001米）的十億分之一。 這個名稱將SI前綴納米（來自古希臘語νάνος，nanos，“矮”）與父母單位名稱計量器（來自希臘語μέτρον，metrön，“計量單位”）結合起來。 它可以用科學記數法寫成1×10-9米，工程記數法為1E-9米，僅為10億米。

The metre (international spelling) or meter (American spelling) (from the Greek noun μέτρον, "measure") is the base unit of length in the International System of Units (SI). The SI unit symbol is m. The metre is defined as the length of the path travelled by light in a vacuum in 1/299 792 458 seconds.
