I've been re-learning metric and imperial conversions and know the basic rules of:
1 ft = 0.3048 m
1 m = 3.2808 ft - Metric = feet
Imperial = Metres
I've rounded them down to 0.304 and 3.28 for calculating.
Have I got the calculations correct for these questions? A lorry measures 32 feet 6 inches. How long is it in metres?
32.6 ft x 0.304 m = 9.9104 m [rounded to 2 d.p. as 9.9 m]
and A road prohibits vehicles over 2.1m wide from entering. What width in feet would a vehicle be, in equivalent feet?
I did this calculation:
2.1 m x 3.28 ft = 6.888 ft [rounded to 2 d.p. as 6.8 ft]
The vehicle would have to be over 6"8 to enter.
Also, what's the major difference between these numbers:
32.6ft
32ft 6 inches
6.6ft
6ft 6 inches
Does it matter how it's written when doing a calculation to ensure you get the correct answer?
In general, is the rule to multiply for larger units, divide for smaller units for this sort of calculation?
I would appreciate any advice on this just to make sure got things right.
