On the manufacturer's website, it states that a level scoop of Taurine powder contains 250 mg of taurine.

You mention mcg, but I assume you meant mg? In that case, you can divide the powder from a level scoop into five equal portions, allowing you to take 50 or 100 mg.

Please be aware that with a daily intake of 50 mg, the packaging will last for 5000 days (250 grams = 250,000 mg). At 100 mg per day, this is approximately 7 years. However, once opened, the packaging does not last that long. It is best to consume jars containing powder within about a year. Powders tend to clump over time.

You can safely take up to 1000 mg of taurine per day (four scoops), meaning the jar will be empty within 8 months.

Always open the jar in a dry area and ensure that the lid is securely closed each time. Do not open the jar with damp hands.

If you have an empty jar available, you can transfer a week's worth of supply into it, so you don't have to open the original jar daily. This way, the contents will last much longer.

Yes, you can. With a kitchen scale, you could first weigh out a gram of the Taurine powder, and then divide that gram into, say, ten equal parts, so you get an idea of how much 100 mg is approximately. It will likely be a small pinch.
