Unit	Symbol	In meters	Common use
Meter	m	1 m	SI base unit
Kilometer	km	1,000 m	distance, driving
Centimeter	cm	0.01 m	height, sizes
Inch	in	0.0254 m	screens, specs
Foot	ft	0.3048 m	US height, building
Yard	yd	0.9144 m	sports, fabric
Mile	mi	1,609.344 m	US & UK roads
Nautical mile	NM	1,852 m	marine & aviation

Example: 5 miles to km → 5 × 1,609.344 = 8,046.72 m → ÷ 1,000 = 8.047 km. For the reverse direction, divide by the same factor.
