Weights, measures and conversions
Imperial to Metric fluid conversions
I prefer to use metric measures because they are always consistent. The pints here are British pints (600ml) , not American pints (16 fluid ounces). Naming confusion can lead to a lot of messed up recipes.

| Teaspoon / Tablespoon Measure | Metric |
| ¼ tsp | 1.5ml |
| ½ tsp | 2.5ml |
| 1 tsp | 5ml |
| 1 tbsp | 15ml |
The tablespoon (tbsp) measure here is a British/American tablespoon. Australian tablespoons are 4 tsp (20ml). Take note of this when following Australian recipes. When possible, look for recipes using metric measures or weights.
