Conversion to US Customary Units measurements
If you are more familiar with the US Customary rates (for example: lbs/ac. or mph) the following conversion system
will be convenient. To find the rate of lbs/ac. calculate the given rates in kg/ha (kilograms per hectare). Example:
CAN 27%N
1 ha
= 2.47 ac.
300 kg/ha – 15 m – 12 km/h = Shutter 35
1 ac.
= 0.405 ha
kg/ha x 0.89 = lbs/ac.
1 kg
= 2.205 lbs
m
x 3.28 = ft
300 kg
= 661.5 lbs
km/h x 0.62 = mph
300 kg/ha
= 267.8 lbs/ac.
267.8 lbs/ac. – 50 ft – 7.5 mph = Shutter 35
