Formula
To convert teaspoons Baking Soda (teaspoons) to ounces Baking Soda (ounces): Multiply teaspoons by 1.08 (density of Baking Soda)
About teaspoons Baking Soda (teaspoons)
Teaspoons of Baking Soda. Measured by US teaspoon (= 5 mL = 1/3 US tablespoon = 1/48 US cup per FDA 21 CFR 101.9). The teaspoon is the standard US measure for small dry ingredients (salt, sugar, baking powder, spices) + small liquid amounts (vanilla extract, lemon juice). Common multiples: 1/4 tsp (1.25 mL), 1/2 tsp (2.5 mL), 1 tsp (5 mL). 'Heaping teaspoon' is informally ~50% more than level (can vary widely). Most US measuring-spoon sets include 1/4, 1/2, 1, and 1 tablespoon (= 3 tsp) increments. Baking soda (sodium bicarbonate, NaHCO₃) is a pure chemical leavening base — a single ingredient, not a blend like baking powder. Density ~1.080 g/mL (slightly denser than table salt). Requires an acidic ingredient in the recipe (buttermilk, yogurt, vinegar, lemon juice, cocoa powder, brown sugar's molasses, honey, fruit juice) to react and release CO₂ gas for leavening. The reaction is immediate upon mixing with the acid + moisture, so batters must be baked promptly. Common ratio: 1/4 teaspoon baking soda per 1 cup flour for recipes using ~1 cup acidic ingredient (buttermilk pancakes, banana bread). Excess baking soda produces a soapy/metallic flavor + brown spots. Non-baking uses: deodorizing refrigerators, scrubbing pans, brushing teeth, antacid for heartburn relief, fire suppression (kitchen grease fires), pool pH balancing. Major US brand: Arm & Hammer (since 1846, the iconic orange box). Shelf life ~2 years sealed; ~6 months opened. Test viability: drop 1/2 tsp in 1 tbsp vinegar — should fizz vigorously. Density: 1.080 g/mL (used to convert volume measurements to mass).
About ounces Baking Soda (ounces)
Ounces of Baking Soda. Measured by US avoirdupois ounce (= 28.349523125 g exactly per NIST SP 811 — distinct from fluid ounce which is a volume unit). Mass-ounce measurement is preferred in US butcher/bakery/professional contexts where precision matters but the recipe uses imperial customary units. Common US baking ingredient packages list both ounces (mass) + grams: a stick of butter = 4 oz = 113 g; a 'pound' of flour = 16 oz = 454 g. CRITICAL: do NOT confuse with the troy ounce (~31.1 g — used only for precious metals) or the fluid ounce (volume unit = 29.57 mL).
