@@PharmaScholars Hello madam, hope you are doing well. Let me know that in repeatability there is a statement that if SD is less than 0.41d, then we should use 0.41 x least count of balance for calculations. So in which unit we have to take value of d. In g or mg ?
It depends upon the least count of respected weighing balance. Your least count is the minimum value display on your weighing balance. Suppose it is 0.1mg, then unit will be mg, & if it is 0.1g then unit will be g.
Hello sir, hope you are doing well.
Let us know, how we can find out the smallest net weight & is there any formula given in USP general chapter?
Yes dear, there is a formula , I have mentioned in this video. Check it out @ 7:38

Thnk u for your reply madam, but we convert both mg to g and g to mg. My question for calculation which unit we should use ?
U can use any unit as per your requirement, but calculation will be easy if you use same unit as mentioned as d value.
Thank you❤
Welcome dear
if u wiil explain with practically in excel its much better for understand
Sir,
Why 0.41 using and where it omes from
This is a standard factor given by USP.
