Convert baking soda weight to spoon measures or volume to mass using mg, g, oz, US tsp, metric tsp, tbsp, or mL using a disclosed spoon-weight assumption or your measured grams per US teaspoon.
Common Mistakes Quick tips
- Choosing the wrong conversion direction. Select mass to spoon measure or spoon measure to mass, then enter the displayed input.
- Using water-based conversions for powders. Baking soda’s volume varies with brand, humidity, and packing.
- Mixing US and metric spoons. US tsp = 4.92892 mL; Metric tsp = 5 mL; US tbsp = 14.7868 mL.
- Treating scant, rounded or heaping spoons as fixed quantities. Weigh your own spoonfuls and enter measured grams per US teaspoon when available.
- Confusing baking soda with baking powder; they are different ingredients with different densities and uses.
When to Use This Calculator
- Converting package weights (mg, g, oz) to kitchen measures (tsp/tbsp) for recipes.
- Standardizing recipe cards across US and metric kitchens.
- Scaling amounts when only a spoon measure or a weight is given.
- Quick estimating when you don’t have a scale handy (best accuracy comes from weighing).
Input Definitions
- Baking Soda Mass — choose mg, g, or oz; 1 oz = 28.349523125 g.
- Volume — choose US tsp (4.92892 mL), Metric tsp (5 mL), US tbsp (14.7868 mL), or mL.
- Measured spoon weight — optional grams per US teaspoon for your product and filling method. Blank uses 4.6 g; unsupported fixed compaction presets are no longer used.
- Assumption — Level US tsp of baking soda ≈ 4.6 g; results are estimates due to packing and particle size.
Baking Soda Weight ↔ Teaspoons (Approx.) Formula
The following formulas estimate baking soda mass in milligrams and US teaspoons using the existing estimate of 4.6 g per level US teaspoon. If you enter a measured spoon weight, p in the formulas below equals that weight divided by 4.6 g. Powder volumes vary—use a kitchen scale (or check your product packaging/brand reference) for best accuracy.
- Assumption: level US teaspoon of baking soda ≈ 4.6 g (4600 mg); p = measured grams per US teaspoon divided by 4.6, or 1 when the optional field is blank.
- US teaspoon = 4.92892 mL; Metric teaspoon = 5 mL; US tablespoon = 14.7868 mL (3 US tsp).
- 1 ounce (oz) = 28.349523125 g.
How do you convert mg of baking soda to teaspoons? Divide milligrams by 4600 and adjust for packing p: tsp = mg ÷ (4600 × p); for a level spoon use p = 1.0.
How do you convert teaspoons of baking soda to mg? Multiply teaspoons by 4600 and packing p: mg = 4600 × p × tsp; for level teaspoons set p = 1.0.

| * Assumes level US teaspoons at 4.6 g (4600 mg) per tsp. For a measured spoon weight d in grams, use p = d ÷ 4.6. This table uses the default estimate; it is not a universal density. | |
Example Problem
Convert 2300 mg of baking soda to US teaspoons (level).
Use the formula: tsp = mg ÷ 4600.
tsp = 2300 ÷ 4600 = 0.5 tsp
