Batch Scaling Around 30g Water
| Batch Scale | Weight (g / oz) | US Cups & Spoons | Metric (mL) |
|---|---|---|---|
| Half Batch (0.5×) | 15g (0.53 oz) | 1 tbsp | 15 mL |
| Standard (1×) | 30g (1.06 oz) | ⅛ cup | 29.9 mL |
| 1.5× Batch | 45g (1.59 oz) | 3 tbsp | 44.9 mL |
| Double Batch (2×) | 60g (2.12 oz) | ¼ cup | 59.9 mL |
| Triple Batch (3×) | 90g (3.17 oz) | ⅓ cup + 2 ¼ tsp | 89.8 mL |
Measuring 30g of Water in the Kitchen
Because 1 US Customary Cup (236.6 mL) of water weighs 237g when measured poured liquid, 30 Grams (30g) translates to 0.13 US cups (⅛ cup).
Without a kitchen scale, measure ⅛ cup (2.03 tablespoons total) using poured liquid technique. Place a liquid measuring cup on a flat countertop and read the water meniscus at eye level. Standard water has a pure density of 1.00 g/mL, making 1 US cup exactly 237 grams (or 236.6g).
Source note: NIST Standard Reference Data; 1 US customary cup = 236.588 mL = 236.6 g pure water at 20°C
