Question

The Air Force One (Boeing 747-200) has a long-range mission takeoff gross load 833,000 pounds (Ibm). What is Air Force One's takeoff mass in: a. gram (9) b. kilogram (kg) c. tonne (ton) d. Mton

Answer 1

The mass in:

1) Grams =
`377765.5* 10^(3)grams`

2) Kilograms =
`377765.5kilograms`

3)Tonnes =
`377.7655tonnes`

4) Megatonnes =
`0.378megatonnes`

Explanation: The given mass of the aircraft in pounds is 833,000 pounds.

Part 1)

Since we know that 1 pound equals 453.5 grams thus by ratio we have

833,000 pounds =
`833000lb* 453.5(g)/(lb)=377765.5* 10^(3)grams`

Part 2)

Since we know that 1000 grams equals 1 kilogram

thus the above mass in kilograms equals
`(377765.5* 10^(3))/(1000)=377765.5kg`

Part 3)

Since there are 1000 kilograms in 1 tonne

thus the given mass is converted into tonnes as

`mass_(tonnes)=(377765.5kg)/(1000)=377.765tonnes`

Part 4)

Since 1 Mega tonne(Mton) equals 1000 tonnes thus the given mass is converted into mega tonnes as

`mass_(M\cdot tonn)=(377.7655tonnes)/(1000)=0.378Megatonnes`
