Inherited a handwritten family recipe, or found an old cookbook that calls for "a gill of cream" or "butter the size of an egg"? Before standardized measuring cups and spoons became common kitchen equipment in the mid-20th century, recipes described amounts using everyday objects and older units. Here's what each one actually means today.
Volume Terms
| Term | Modern Equivalent | Notes |
|---|---|---|
| Gill | ½ cup (4 fl oz / ~120 ml) | Standard British/early American liquid measure |
| Teacup | ~¾ cup (6 fl oz) | Approximate — actual cup sizes varied |
| Coffee cup | ~¾-1 cup (6-8 fl oz) | Approximate, slightly larger than a teacup |
| Wineglass | ¼ cup (2 fl oz) | Common in older sauce and dessert recipes |
| Tumbler | 1 cup (8 fl oz) | Refers to a standard drinking glass of the era |
| Breakfast cup | ~1¼-1½ cups (10-12 fl oz) | British term, larger than a standard teacup |
Butter and Fat Terms
| Term | Modern Equivalent | Notes |
|---|---|---|
| Butter the size of an egg | ¼ cup / 4 tbsp (~55-60g) | Based on a large egg's approximate volume |
| Butter the size of a walnut | 1-2 tbsp (~15-25g) | Smaller reference, common for finishing sauces |
| Knob of butter | ~1 tbsp (~14g) | British term, still used informally today |
| Lump of butter | ~2 tbsp (~28g) | Roughly double a knob |
Small-Quantity Terms
| Term | Modern Equivalent | Notes |
|---|---|---|
| Saltspoon | ¼ tsp | A small dedicated spoon for salt, not a teaspoon |
| Dessertspoon | 2 tsp | Between a teaspoon and a tablespoon |
| Pinch | ~1/16 tsp | What you can hold between two fingers |
| Dash | ~1/8 tsp (liquid) | A quick, brief pour — mostly for liquids/seasoning |
Produce and Dry-Goods Terms
Older recipes and grocery lists sometimes measure produce and bulk dry goods in units that predate the pound or the cup entirely — these show up more in ingredient lists ("a peck of apples for the pie filling") than in the mixing instructions themselves.
| Term | Modern Equivalent | Notes |
|---|---|---|
| Peck | 2 dry gallons (~8 dry quarts) | Common for apples, potatoes — a peck of apples is roughly 10-12 lbs |
| Bushel | 4 pecks | Standard wholesale/farm-stand produce unit, rarely used in a home recipe itself |
| Cupful / spoonful (vs. "cup" / "spoon") | Same volume, older phrasing | "Cupful" and "cup" mean the same measured amount — the "-ful" suffix was simply the standard 19th/early-20th-century way of writing it |
Unlike the cup-based terms above, a peck or bushel isn't something you're meant to precisely portion into a mixing bowl — recipes calling for these are usually describing how much raw produce to start with (before peeling, coring, or trimming), not a mixed-in ingredient amount.
Why Recipes Used Object-Based Measurements
Standardized measuring cups and spoons didn't become common American kitchen equipment until the early-to-mid 1900s, popularized in large part by Fannie Farmer's cookbooks. Before that, home cooks measured against whatever consistent household objects they had — a teacup, a wineglass, an egg — since those were more universally available than a calibrated cup. The imprecision was accepted as normal; recipes assumed a cook's practiced eye would adjust as needed, which is part of why older recipes read as less exact than modern ones.
A Note on Precision
These conversions are widely accepted approximations, not laboratory-exact figures — a "teacup" genuinely varied by household, and "butter the size of an egg" depends on the egg. For baking, where precision matters more, err toward the lower end of any range given here, and adjust by taste and texture as you go, the same way the original cook likely did. If a recipe uses several of these terms together — a gill of one ingredient, a teacup of another, a coffee cup of a third, the way British recipes commonly did — that's not inconsistency on the writer's part; each term was doing a specific job, roughly the same way a modern recipe uses teaspoons for small amounts and cups for large ones.

Frequently Asked Questions
What is a gill in cooking measurements?
A gill is ½ cup, or 4 fluid ounces (about 120 ml). It was a standard liquid measure in British and early American recipes and shows up most often in older baking and sauce recipes.
How much butter is "the size of an egg"?
About ¼ cup, or 4 tablespoons (roughly 55-60 grams). This was a common way to specify butter before measuring cups were standard kitchen equipment — a large egg's volume is a reasonably consistent, easy-to-picture reference.
What is a teacup measurement in old recipes?
Roughly ¾ cup (6 fluid ounces), based on the size of a standard British teacup. It's less precise than a gill or a modern measuring cup since actual teacup sizes varied, so treat it as an approximate historical reference rather than an exact measurement.
What's a "peck" of apples or potatoes in modern terms?
A peck is 2 dry gallons, or about 8 dry quarts — for produce like apples, that's roughly 10-12 pounds depending on size and variety. It's a bulk-quantity term for raw produce (how much to buy or start with), not a mixed-in ingredient amount like the cup-based terms above, so you won't typically see it inside a recipe's actual instructions, only in the ingredient list.
