Formula

fm = km x 1.0E+18

Quick Rough Maths

To get the Fermis, multiply the number of Kilometres by 1000000 trillion

Kilometres (km) in 1 Fermi

There are 0 Kilometres in 1 Fermi

Fermis (fm) in 1 Kilometre

There are 1.0E+18 Fermis in 1 Kilometre

Symbol: **km**

Unit System: SI

Unit System: SI

The kilometre is a unit of length and is a multiple of the metre; an SI derived unit. It has the symbol km.

A kilometre is equal to 1000m, 1094 yards and 0.621 miles.

Kilometres is used to measure road distances in the US, though the UK is still using the imperial "sister" miles.

Symbol: **fm**

Unit System: Non-SI metric

Unit System: Non-SI metric

The fermis is a unit of length in the non-SI metric system and uses the symbol fm.

One fermi is equal to 1×10−15m or 3.9370×10−14 in.

It is used to measure nuclear distances and was named after the Italian physicist Enrico Fermi (1901–1954). It has now been replaced with the SI-derived term femtometre.
