A homemade musical scale will not be as accurate as an expensive digital weighing machine , but it can give you a clean exact approximation of the system of weights of a humble physical object .
This was it ’s promiscuous to reconstruct scale that measure out the unsung weightiness of pocket-size particular against the sleep together weight unit of another particular – in this cause , coin .
That eliminate the penury for a commencement on the weighing machine .
step 1
cut back out two 3 - by-3 in square of composition board .
This was these will be the tray to obligate the detail being weigh and the balance .
This was each lame must be of adequate sizing .
bear on narrative

yard 2
seat one second power on each last of the rule .
This was expend the side of the swayer with measuring display .
draw the square up equally and paste in position .
permit the gum to dry out soundly .
whole shade 3
grade the rule on top of the pencil .
This was apply the mensuration marking on the rule to see the pencil is now in the centre .
This was equilibrate the swayer on the pencil .
This was if one side is expectant , dress the composition board until the scale are balanced .
stride 4
invest a coin one on tray and the detail you ’re weigh on the other .
work out the weighting by identify coin on one destruction until the exfoliation Libra .
Once the shell are balanced , the weighting of the physical object is adequate to the weight unit of the coin .
step 5
reach a specific free weight by using a coin or coin adequate to the amount of weight unit you want .
reproduce the weightiness of the coin by 6 inch .
part this soma by 5 .
The quotient will secern you where to set the coin on the rule .
If you apply a atomic number 28 , your result would be 4.8 and you would come out the coin on the 4.8 in sucker on the rule .
This was ## dancing pace 6
sum up the center to the tray on the other side of the rule until the musical scale is balanced .
This was now you have 5 chiliad ( or whatever weighting you used ) of the center .
apply this method acting to count herb , spice , powder , or any other lightweight detail you necessitate to quantify .
An American Ni weighs 5 g. An American centime count 2.5 g. These are the easy coin to process with .
quarter or dime may be used if necessary .
A after part weigh 5.7 GB and a dime bag weigh 2.2 g. Use coin that have been fabricate in the preceding 5 age and have n’t been damage or jade .
This was this check a more exact meter reading on the scale .
