For all of us out there that just needs to measure their rocket fuel right now and can't wait. Or if you're like me who can't imagine spending money on a sale you won't use 99.9999% of the time. Here is how you can build one using your MacGyver skills and ordinary office supplies.

Step 1: Parts List

2 sheets of paper
2 large books
<p>In the time it took you to construct a half-assed gram scale at the office in order to weigh out your 'Rocket Fuel', your company has paid you enough money to buy SEVERAL cheap, inexpensive digital scales. Now, I understand that the present cost of 'Rocket Fuel' forces us to cut back in other areas in order to meet the growing demand for more. And more... HOWEVER.. At this point, I'LL bet you're kicking yourself in the ass, wondering: &quot;Gods, how much 'Rocket Fuel' HAVE I purchased overall? Have my suppliers been bamboozling me this WHOLE TIME? How many grams have they stolen from me?!? SURELY I could afford a $12.00 digital scale by now?!?!?! Something's wrong...&quot; Never fear, I have a solution for you, friend.. GET BACK TO F*#@ING WORK, cuz you suck at buying and selling 'Rocket Fuel'. </p>
oh, and you can find coin weights in wikipedia! (At least for euros)
That's almost like my idea! I managed to measure weights in 10mg accuracy. I use a transparent ruler and I simply balance it on a triangular ruler (http://www.woodrow.net/oneProduct.asp?productId=38). I simply put the coin on the ruler (the ruler on my construction is horizontal) on one side and the thing I want to weigh on the other, suspended on a thin string from the edge of the office. I measured the accuracy by using the scale to measure the weight of some coins with other coins. I'll sometime make an instructable for mine too, the good thing about mine is that it doesn't use tape(exept for the cointainer of the item to be measured). Well done for your scale too! I wanted to see if someone else thought about it and posted it.
&nbsp;at least there's a formula for this
I like the part about coin weights! Very informative.
Cool idea! The only problem with using packaged food for the known weight is that that should be the weight of the food not including the packaging. If You were to use the ketchup bottle then your weight would be off considerably if it was a glass bottle. It would probably work using a dry good dumped into your matching weight trays though. I'm sure this will come in handy some day!
