From unit conversion, it is found the following results:

6km ≈ 3.73 mi

2.5 L≈ 0.66 gal

90 lb ≈ 40.82 kg

Unit Conversion

Units of measurement are part of our daily lives. There are different units for area, length, volume, mass, and others.  Because of this, it is important to know converting them.

For solving this question you need some information as:

1 km = 0.621371 mi ( unit for length and distance)

1 L = 0.2641722 gallons (unit for volume)

1 lb = 0.453592 kg (unit for mass)

Therefore,

  • If 1 km = 0.621371 mi, you will have:

           1 km --------  0.621371 mi

           6 km --------  x mi

           x= 6* 0.621371

           x=3.73 mi

Thus, 6km ≈ 3.73 mi.

  • If 1 L = 0.2641722 gallons, you will have:
  •            1 L--------  0.2647122 gal
  •           2.5L --------  x gal
  •            x= 2.5* 0.2647122
  •            x=0.66 gal
  • Thus,
  • 2.5 L≈ 0.66 gal.
  • If 1 lb = 0.453592 kg, you will have:
  •            1 lb--------  0.453592 kg
  •           90 lb --------  x kg
  •            x= 90* 0.453592
  •            x=40.82 kg
  • Thus,
  • 90 lb≈ 40.82 kg
  • .
