My scale weight is by the 16th of oz.
All the recipes I look at are in 100 example 4.27oz or 11.97oz.
How do I handle the .97 to oz?

I converted that to grams and not sure 86.89717 is either.

I would probably round .97 oz up to 1 oz.

What if it is .41 or .65

If you are not using a digital scale, you need to be. The old analog kitchen scales are not accurate enough for soaping. You need something that will even measure grams.

However, the rule of thumb is to round up on oils and down on lye.

What I do is if it's under 50 I round down and if it's over 50 I go up. Except with lye I always round down. HTH

I always use grams. It's the most accurate measure

Yep grams are the easiest, then when you have something in percentage it is the easiest to convert to weight) Metric , metric is the queen )

Also, most soap calculators have a grams option. Just click that, and go from there.

If it is .45 - .49 round up to .5; if it is .44 or less round down to .4

At my work when we convert to grams it's 453.6grams to a pound so .97oz= 0.060625#. 453.6*.060625=27.4995Grams we would round that to 27.5grams.
