Answer:
It will be equivalent to 338.95 N-m
Explanation:
We have to convert 250 lb-ft to N-m 
We know that 1 lb = 4.45 N 
So foe converting from lb to N we have to multiply with 4.45
So 250 lb = 250×4.45 =125 N 
And we know that 1 feet = 0.3048 meter
Now we have to convert 250 lb-ft to N-m 
So 
So 250 lb-ft = 338.95 N-m
