1. Let’s convert 4.56 mi into km.
First we write down our given
4.56 mi
1 ft = 12 in
1 mi = 5280 ft
1 lb = 16 oz
1 gal = 4 qt
1 in = 2.54 cm
1 mi = 1.61 km
1 lb = 454 g
1 L = 1.057 qt
1 m = 100 cm
1 km = 1000 m
1 kg = 1000 g
1 L = 1000 mL

1. Let’s convert 4.56 mi into km.
Then we multiply it by a conversion factor that gets rid of mi and
replaces it with km. This would need to have mi on bottom to
cancel them out, and km on top
4.56 mi
1 ft = 12 in
1 mi = 5280 ft
1 lb = 16 oz
1 gal = 4 qt
1 in = 2.54 cm
1 mi = 1.61 km
1 lb = 454 g
1 L = 1.057 qt
1 m = 100 cm
1 km = 1000 m
1 kg = 1000 g
1 L = 1000 mL
