Here is a photo that you may find useful to be sure Ringo is in fact a He. I was able to check by getting mine onto my fingers and then slowly spreading my fingers apart so I could look at the underside. Might work if Ringo isn't really active.
Aside from that, you would be surprised at how tough it is for us humans to guess at small weights. My female weighs just over 40 grams but feels like she isn't even there when I hold her. Like Jess said, the kitchen scales at walmart are great. Plus it helps us keep track of weight gain, feeding issues, etc. I have a notebook for each Leo that are full of daily info on weights, how much they ate, even if they pooped. If we ever have to take our Leo to a vet, it is a great idea to give them as much info as possible.
I hope the orange does come through more

I love the tangerine and sunglow morphs. Have been thinking about getting one when I have the space.
