To convert feet to meters: multiply by 0.3048. To convert meters to feet: multiply by 3.28084.
1 ft = 12 in = 0.3048 m = 1/3 yd = 30.48 cm.
For example, 1 Foot (ft) = 3.048000e-19 Exameter (Em).

The foot is a unit of length equal to 12 inches or exactly 0.3048 meters.
1 ft = 12 in = 0.3048 m = 1/3 yd = 30.48 cm.
To convert feet to meters: multiply by 0.3048. To convert meters to feet: multiply by 3.28084.

The international foot (0.3048 m exactly) differs slightly from the US survey foot (1200/3937 m), which was deprecated in 2023.
Confusing the foot with 30 cm (it's 30.48 cm). Also, forgetting that 5′10″ is not 5.10 feet — it's 5 feet 10 inches = 5.833 feet.
There are 3 feet in a yard and 5,280 feet in a mile. A 6-foot person is about 1.83 meters tall.
The exameter is a unit of length equal to 10¹⁸ meters, or about 105.7 light-years.
1 Em = 10¹⁸ m = 1,000 Pm ≈ 105.7 light-years ≈ 32.4 parsecs.
To convert Em to light-years: multiply by 105.7. To convert Em to parsecs: multiply by 32.4.
No practical applications. Theoretical framework for expressing galactic neighborhood distances.
The Milky Way galaxy has a diameter of about 10 Em (100,000 light-years).
Em is almost never used — astronomers use parsecs or light-years. It exists only for SI completeness.
Just remember: Exa = 10¹⁸. The Milky Way is about 10 Em across for a sense of scale.
