Units explained
Megaparsec
A megaparsec is a distance unit equal to one million parsecs (about 3.09×10²² m). It is the standard unit for cosmological-scale distances.
Combines the metric-style prefix mega- with the parsec. Standardised in astronomy for inter-galactic distances and cosmological calculations.
Megaparsecs are used in cosmology to express distances to other galaxies (Andromeda is ~0.78 Mpc), galaxy-cluster separations, and the Hubble constant (typically quoted as ~70 km/s per Mpc).
Exact via the parsec; the megaparsec is the standard scale unit in modern cosmology.
Foot
A foot is an Imperial and US customary unit of length equal to 12 inches or exactly 0.3048 meters. It is the most commonly used unit of length in everyday measurement in the United States.
The foot's origin is literally the length of a human foot, used as a measurement standard since antiquity. The English foot was standardized at various points in history; the modern international foot (0.3048 m exactly) was fixed by the 1959 International Yard and Pound Agreement.
Feet are used in the US for body height, building dimensions, room sizes, road sign clearances, aviation altitude (feet above sea level), and most everyday distance estimation. The UK uses feet informally for height despite officially being metric.
Used since antiquity; standardized to 0.3048 m exactly by the International Yard and Pound Agreement of 1959. Aviation worldwide uses feet for altitude despite metric adoption elsewhere.
Megaparsec to Foot conversion formula
The relationship between megaparsecs and feet:
To convert megaparsecs to feet, multiply the value in megaparsecs by 1.012361e+23. To reverse, multiply feet by 9.877895e-24.

Step-by-step: convert megaparsecs to feet
- Write down the value in megaparsecs (Mpc).
- Multiply that value by the factor 1.012361e+23.
- The product is the equivalent value in feet (ft).
- To reverse, multiply the foot value by 9.877895e-24.
Worked examples
Example 1 — Convert 1 Mpc to ft:
1 × 1.012361e+23 = 1.012361e+23 ft
Example 2 — Convert 100 Mpc to ft:
100 × 1.012361e+23 = 1.012361e+25 ft
