Thank u soo so much . i have been searching scale bar video for many days ..now i found u .

[@galathilion]

Hey guys, if you don't have some measurement in um in your picture, you won't be able to do it (you have nothing to compare against). You have to add a scale in um first. You should have it (or be able to get it) from the previous program you used to take the image. And if the picture was given to you, it should have a scale somewhere, or you should ask for it. Once you do that, you can follow this explanation, which by the way, was really good. Thank you!

Hi, thanks for explanation, I have SEM image without scale bar. How can I measure the correct particle size?

[@luiszambrano1740]

Thanks so much!

[@saraaval9722]

If you look at the image properties, It seems Fiji can display the correct scale by itself. So I am confused why you are not simply using that. Is there something that I am missing? is it related to the version you used in 2017? Thanks

How to put place "um" on the scale bar, rather placing below the line. Because in my all other images letters "um" are below the scalebar

[@user-mc5en8xf8p]

Thank you! Very clear and helpful! How do you put greek symbol 'mu' on the keyboard?

[@buddha102]

alt + 230 = µ

[@dipmanikumar7961]

Just write mu in unit

[@psycogirl89]

hello
I didn't get why do you set 50 um instead of 10 um as the original image?

[@deepakdeshmukh8853]

was there any reason to choose 50 in the length section and 5 in the height of pixel section? or was that random??

[@parthasarathisubramanian2539]

You can give any length.

[@dharmendrasinghrajput330]

from where have you got the standard 10 micro meter scale on the image, to set the parameters?

[@nirolf12]

It's standard from the SEM software

[@fadurecipes]

Thank you sir
Sir how to put letters like void or other word on sem image

[@neurosyd9985]

how did you get the 10 microns already on your image?

[@nirolf12]

It's standard from the SEM software

[@Engr_Muhammad_Ahmed]

Sir I'm unable to change the scale. In my laptop, only pixels scale show. My question is that how is it convert into micrometers?

[@galathilion]

@@mjaykr But how? Only pixels show, thus, we don't have um to calibrate or compare.

[@naina7112]

I am confused, how you know it is around 60 pixels?

[@kurarisanamie]

I think he just rounded the 59.833 into 60. it is just a mathematical thing

[@AnilKumarSharma-ys6jw]

Save karne uspe scale show nahi karha hai please

[@happys2458]

[@kagomealmariha]

Try to save it in a png format
