How To Calibrate Digital Pocket Scales WITHOUT a Calibration Weight

This video shows you how to calibrate a set of digital scales without a weight by using 14 x 2p coins (United Kingdom) or 20 x nickles (USA) to replace a 100g calibration weight

***USA 20 x nickles (5 cent coins) = 100g***

14 x 2p coins = 99.5g
(This is not exactly 100g but will work in emergencies. The difference will only be 0.005g per gram which is nothing really)

The calibration process is very similar to the one show in the video for most scales however just search for the manual online for the correct procedure & the calibration weight needed.
Usually the scale will display the required weight during the calibration process (As shown in the video)

1. Turn Scale On
2. Press and hold CAL button or MODE/UNIT button until CAL or weight needed is displayed (You may need to release & press it again as in video)
3. Place weight on scale. The scale should show PASS or F (You may need to press CAL/MODE button again)
4. Remove weight. ( You may need to turn scale off)
5. Finish!

If you need a larger weight just multiply the number of coins

7 x 2p = 50g
14 x 2p = 100g
28 x 2p = 200g

    My scales max100g but when I try to calibrate them it keeps saying 50.00g I only have a 100g calibration weight.?!?

  • David Garay - January 13, 2018 reply

    What if you placed something heavy and passed the weight limit? Now when I turn it on it moves from -1 to 0 to 1. Doesn't stay still even with nothing on it.

  • lewis kavanagh - January 13, 2018 reply

    worked for me

    i just got it mine say 0-Ld what does that mean

  • Randy Robinson - January 13, 2018 reply

    If you need a set of calibration weights let me know. i have 4 different sizes starting at 10g,, 100g, 200g, and a 500g, for 4 US dollars. just let me know.

  • Randy Robinson - January 13, 2018 reply

    LMAO This is proof our schools are failing us, and these young people are too ignorant to take care of themselves.

  • Myke D - January 13, 2018 reply

    These things blow. Unless you happen to have a 200 gram weight laying around it's impossible to calibrate. The coin thing didn't work for me

  • Jade Rose - January 13, 2018 reply

    mine dont say cal….just 100g

  • Randy Robinson - January 13, 2018 reply

    you can not use coins to calibrate, they don't weigh the same. That much accuracy to construct a simple coin, would be stupid expensive, and accuracy reserved for moon rovers.

  • AA To The Stage - January 13, 2018 reply

    mine says error when I try to calibrate it

  • oke rhrh - January 13, 2018 reply

    wow man I got exactly the same scale.. could you help? yday it just said 0.0 and didnt change and when i try to calibrate it just stays on cal.. doesnt day 100.0 like your one.. plus obviously it doesnt weigh anything.. help please?

  • dezza72 - January 13, 2018 reply

    scales need to be exact, therefore need exact weights for calibration.

  • WilBillson - January 13, 2018 reply

    we used to use 2p for a 7gram weight and obviously a penny for an eighth///3.5 g. just been testing that now and found that different 2 p's vary by sometimes as much .4. Then I cleaned them back to shiny and still found slightly less fluctuations. Hardly anything to cry about. I suspect that fresh minted coins will still vary a bit. Obviously banks weigh coins when buying/selling them.

    safe lad I just got one of these for my off the books business

  • brendan thompson - January 13, 2018 reply


  • Colin Hadley - January 13, 2018 reply

    I think you're incorrect… a 2p weighs 7.12g
    14 of them would be 99.68g

    Similarily, 7x = 49.84g

  • ed ortiz - January 13, 2018 reply

    I have had a problem with my AWS Lb-1000 scale 2times in the last 4 years.. Goole the manual for your scale. it will tell u how big of a weight u need.. I got mine at a smoke shop. lost it and now just use dollars.. they weigh 1 gram

  • Steven Curnow - January 13, 2018 reply

    14 x 2p is 99.68g not 100g

  • Boom Bap Original - January 13, 2018 reply

    So basically i put the 2p's on when it is flashing 100g but nothing happens. Had this problem before can't remember what i did. It's saying 0Ur2. Any help would be greatly apprciated.

  • dym - January 13, 2018 reply

    20 x 20p for 100g, or 10 x 20p for 50g, is actually more accurate. 2p's weigh 7.12g, so 7 of them is 49.84g and 14 is 99.68g; whereas 20p's weigh 5.0g so 10 of them is 50g on the dot. Also, the more coins you use, the more the variation in coin weight is averaged out, so 20p's are a winner in that respect as well. Thanks for the video though – I wouldn't have thought of using coins or looked up the weights if it wasn't for this!

  • Chad Weber - January 13, 2018 reply

    20 us nickels or 40 us pennies(I had to use pennies didn't have 20 nickels lol) works great!

  • Jason Graham - January 13, 2018 reply

    Haw many 2p pls

  • boomkablamo - January 13, 2018 reply

    Coins differ in weight, typically each by a few hundredths of a gram. I've noticed this with nickels, which is what we use in the US, as they weigh 5 grams each. If you're calibrating a scale which can measure a centigram or more, this method is not reliable.

  • nasir abbott - January 13, 2018 reply

    mine say 500.0 so what should i do?

  • Julio 215 - January 13, 2018 reply

    Please help
    I did the same thing but it doesn't give me the right weight in grams
    I did the same thing you did and my penny weighed way more that 3.5
    Please help
    I have the same exact scale as well
