Just google "grains to grams" and a simple fill in chart comes up. Enter the number and it will convert it for you. I've never seen reloading use grams for either bullets or powder, so I don't know why you're asking about it to begin with.

Good luck to you. There's a lot to learn. Just a bit of friendly advice: double check a lot of what you hear on the internet to make sure it's fact...just to be safe. Get yourself a good reloading manual or two. I'd recommend at least the Lyman 50th Edition and then the Hornday book. Good luck and do it safely.
Grams to Grains:
1.0 gram = 15.4324 grains (close enough)
1.0 grain = 0.0647989 gram (close enough)
Powder charge weights (US system of measure) are normally expressed in grains. One US pound of powder is, as mentioned, just about 7,000 grains of powder.
The only way to know if a scale is telling the truth is to actually weigh a known weight like a good quality test weight and it is best to check the scale at several cardinal points including your desired weigh give or take a little.

Our system of grain weight for bullets and powder uses the Avoirdupois system, one of the old English systems for measuring powders and small amounts of material.
There are 437.5 grains to the ounce, and 7000 grains to the pound.
DO NOT confuse the kernals/flakes of powder (which are called grains. like grains of sand) with the "grain weight".
Metric system uses grams, and the conversion is simple math.

For a new reloader I suggest that you get a scale that reads in grains; the possibility of an error converting grains to grams isn't something you want to happen in your early reloading career!
Although there were some scales being calibrated in grams some years ago coinciding with the government's initiative to switch to metric, it was soon abandoned by handloaders and those scales faded from the handloading scene.
The government initiative did result in medical (and a few other areas) related data being expressed in grams (milligrams), but handloaders evidently were more resistant to change.
None of my current (and not so current) handloading manuals show powder charges in grams...only grains. So it is a no brainer...buy a scale that matches what the load data uses...grains, not grams.

Don't buy anything that wasn't designed for reloading, or very small changes in weight.
Some electronic scales on the market don't increment correctly when trickling powder and can create very dangerous situations.
Even then...
I have two "reloading scales" in my possession that cannot be trusted for doing anything related to powder charges, except for spot checking drops from a powder measure.
One, a Cabela's scale, does not increment most changes that are less than 0.2 gr. I can trickle 40 grains of powder into the pan, and have it read 17 gr (or less).
The other, a Hornady scale, losses its zero constantly, and never in a predictable manner. ...And it was the replacement that Hornady sent me for the first one that did the same thing.
They're decent for sorting cases, bullets, etc.; but terrible for working with powder.
I haven't seen anything that beats a good balance beam scale, for under $150.
...But also has grain equivalents in the load data arrays.
Such as: 2,71 [g], 41.8 [gr]

My Vihtavuori manual does.

I think you may be mistaken. Both my Dillon and Hornady scales calibrate in grams and they're both pretty new.

Hornady and Dillion use Grains
Any good digital scale should include a Tare (zero to your empty container) and be switchable between grains, grams, ounces, etc.
Just because a digital scale is switchable does NOT mean you can or should ever use Grams.
But for weighing powder charges, I recommend a quality, reloading specific, beam scale. I just bought a Redding, for just a little more than Lyman. $90 at Midsouth Shooters Supply.
In 30+ years of reloading I have never used anything other than the grains systems. If you want to convert values: https://www.metric-conversions.org/weight/grains-to-grams.htm
As George W. Bush once uttered: "I sometimes use the Google."

You can cross gram calibration weights off your list of things to buy. I would also skip an electronic scale (they need to be calibrated, and can still go wrong, drift, etc.). Digital does not mean better.
Good scales do not need to be calibrated.
It is much more important to be able to competently measure in grains period.

Rather than flopping around trying to figure out what you need, there are kits available that include what you need. Reddings single stage kit is cheaper than Lyman's. Neither includes gram calibration weights.

The one thing even more important: Reloading Manuals! That should be your first purchase and read it all before you buy anything else. It has all been done before. Use that knowledge.
Go here. Click on 'Weight' then 'More Units' then 'Grains'.

It's really best to forget metrics and just use grains. No North American loading manual is calibrated in metric. Including CC's that are a unit of liquid volume not mass.

FALSE: Cubic Centimeters is a measure of volume (period). It does not need to be liquid, solid, or gas. Powder measures dispense by volume. If they are consistent you can get consistent weights.
Mass is not a unit of measure. Catholics go to Mass on Sundays.
