Divide kg by 1.25 for KG/ha to units of N acre
So in this case 100kg/acre is 197.6 units an acre

100kg N per acre is 247kgN per ha which is (divide by 1.25) 198 units acre.

100 units acre is 125kgN/ha
To convert units/ac to kgN/ha X by 1.25
To convert kgN/ha to units/acre X by 0.8
To convert units/ac to kgN/ha X by 1.25
To convert kgN/ha to units/acre X by 0.8

Assuming N is 34.5% then 100kg ( 2 cwt) per acre is 69 units. Units is calculated by the amount of N in fertiliser multiplied by number of cwts.
To apply 40 units of N per acre.
40 divided by 34.5 ( again assuming N of fert is 34.5%) equals 1.16.
Therefore 1.16 multiplied 50 kg (1 cwt) equals 58 kg/acre needed to supply 40 units.
Of course if you're putting on for instance 20:10:10, then 100kg/acre would supply 40 units of N per acre.

So what's that in cwtkgs/haacre
Then?
Then?
All I want to know is how many bags/acre to put on.(small bags not those 600kg things designed for wusses)
Is that too much to ask?

Near as dammit it works out one little bag (1cwt or 50kg) has as many units as the ratio of N
:K. That was supposed to be P!20:10:10 is 20 units so 2 bags is 2bags times 20 units =40
17:17:17 is 17 units. So 2 bags is 2 times 17=34 units.
That is all per acre btw. So the standard 5 (50kg/100cwt) bags of 20:10:10 would be 100units of N per acre.
Tend to go 4.5 wheat, 3.5 barley, especially if it's had regular FYM.5 bags an acre for wheat
4 bags an acre for barley

That would be units/ha. Divide by 2.47 again to get units/ac.

I always have a dread of telling a member of the younger generation to put on two bags per acre of Nitram on the winter barley. Those of us of a certain age who always worked in bags per acre will know that this would put on 70N per acre. I dread to think what could result from two 600kg bags on an acre.
Just as I always work out seed rates at about one and a half cwt/acre I still instinctively have to convert kg/ha back into units or hundredweights per acre and suppose that I always will do.

Come on then what are they. Or is it a calculator app.

Is there an app to convert hundred weight into kgs ? Or what is the maths needed ?

Much easier to stick with bags per acre or units per acre just like we did in the good old days before all this metrication and the LBGT gender neutral lavatories nonsense.
Then it was safe for children to play outside, as long as Myra Hindley wasn’t about, and you could leave your front door unlocked so that nosey neighbours could drop in and make themselves a cup of tea and put their feet up on your kitchen table.
But I digress, as my mind wanders back to those halcyon days of pikels and Hessian sacks; TVO and flapping belts, milk churns and cutter bar hedge cutters.
The only problem is that if you told anyone under forty years of age to put on three bags per acre of Nitram they would use 1800kg to travel half way round the headland of a ten acre field.
