Conversion Table

In addition to the units conversion table shown next, we have developed a Units Converter utility for quick and easy conversion between the units most frequenctly encountered in Unmanned Aircraft related work.

Imperial to metric

 

 

metric to Imperial

1 ft

=

0.3048 m

1 m

=

3.281 ft

1 US gallon

=

3.785 litre

1 litre

=

0.2642 US gallon

1 Imperial gallon

=

4.546 litre

1 litre

=

0.22 Imperial gallon

1 pound

=

0.4536 Kg

1 Kg

=

2.2046 pounds

1 BHP

=

745.7 watts

1 KWatt

=

1.341 BHP

The web based Units Converter utility can be used to convert between metric and Imperial units of:

  • length
  • area
  • volume
  • weight
  • power
