Agar (powder) ingredient guide →1 teaspoon of Agar (powder) in grams
1 teaspoon of agar (powder) = 2.5 grams. That's based on a 120 g per cup baseline. Because agar (powder) can shift with brand and measuring style, weighing is usually more accurate than measuring by volume.
Answer
2.5 grams
Based on agar (powder) density of 0.5 g/ml

Density data from baking references and our own measurements.Why this conversion varies
Agar (powder) can vary by brand and measuring style.
- Agar (powder) may settle, compress, or pour differently based on handling.
- agar (powder) can shift with temperature and ingredient texture.
- This page uses a consistent 120 g per cup baseline for repeatable conversions.
Why this conversion matters
Agar (powder) can behave differently by brand and handling. Converting agar (powder) with a consistent baseline gives you a more dependable starting point for scaling recipes.
Practical baking use
Plant-based gelling agent extracted from red algae. Vegan substitute for gelatin; common in Asian desserts. Use this conversion as a practical starting point for scaling recipes with agar (powder).
- If consistency matters, verify with a small test batch first.
- Use weight-based measurements when precision is critical.

Recipe Context for Agar (powder)
For chemical leavening: small weight changes alter rise and browning.
For quick breads: over-leavening can cause collapse after oven spring.
For cookies: balance leavening with acid source for predictable spread.
Common Pitfalls
- Switching brands without re-checking weight can change texture and bake time.
- Using volume-only measurements for dense ingredients can overshoot recipe targets.
- Expired leaveners can underperform even when measured correctly.
Brand Variance Example
Baseline on this page: 1 cup agar (powder) = 120g. Real-world range can shift by about 6% because fine powders and leaveners settle during storage, changing cup density.
Example for 2 cups: baseline 240g, common range 226g-254g. If your bake is texture-sensitive, start with the lower bound and adjust after a test batch.
