When creating an item, you’ll have to assign it a unit of measurement. This is the unit it is purchased and inventoried as. There are 3 types of units of measurement in WISK:

  • Volume

  • Weight / Mass

  • Unit / Each

These units of measurement are also used when adding recipes to your menu / POS items (both Food and Beverage).


This is the primary unit of measurement for all of your liquid inventory items. If using WISK Bar, the majority of your items will be measured in volume.

The following volume options are available:

  • Milliliter

  • Liter

  • Fluid Ounce

  • Gallon

  • Quart

  • Pint

Additionally, for ease of use, we’ve included some volume options that are common in recipes. You typically wouldn’t inventory or order items in these units, but will help when adding ingredients to your menu items.

Note: These measurements are based on US customary units

  • Cup (= 8oz, 236.588ml)

  • Tablespoon (= 0.5oz, 14.7868ml)

  • Teaspoon (= ⅙ oz, 4.92892ml)

Weight / Mass

The following weight options are available:

  • Gram

  • Kilogram

  • Pound (Lb)

  • Dry Ounce

The unit of measurement you use for an item will depend on how you purchase it. For example, if you purchase ground beef by the pound, you can set the unit of measurement to pounds, and quantity to 1.

If it’s a packaged item with a set weight, for example, a 5lb bag of carrots, you can select lbs, and set the quantity to 5.

Unit / Each

This unit of measurement is for items that are measured as individual units (may be known as “each” or “EA”) and don’t require a weight or volume.

The following unit options are available (they are functionally the same, you can just select your preference):

  • Units

  • Each

Examples include eggs, bread/buns/baked goods, cutlery, takeout packaging, or other merchandise you may sell at your venue (t-shirts, hats, etc.).

With this type, there's an option to count "sub-units" if the measurement quantity is greater than 1.

For example, if you have large eggs. You could choose to inventory them with a measurement of "1 unit", or you could measure them by the carton by setting the measurement to "12 units". When taking inventory you could count by the carton, or individual eggs.

If you have set a case size for the eggs, you can count them by that as well.

Item Measurement vs Quantity

No matter an item's measurement (750ml, 12oz, a 20lb bag, 1 unit, etc), you will normally enter a quantity in units or cases when adding invoices, taking inventory counts, and more.

When you have a weight-based or volume-based item you should always put an accurate item measurement to get accurate recipes and costing. For example, if you have 12oz or 355ml cans, set that as the item measurement. When counting, you will count it as units and/or cases.

For items that have a clear weight or volume, you should never use the "Unit" unit of measurement.

If you use "Unit" instead of a weight or volume measurement, this will cause issues when trying to add recipes to items on the POS Items page. For example, if you have a liquor bottle with an item measurement of "1 unit", you won't be able to add partial amounts of that item to a recipe.
