What Is A Gram?

In culinary terms, a gram is a unit of weight or mass. Grams are commonly used to measure dry ingredients within the metric system.

The metric system is used in Europe, Australia, most of Africa, Canada, and most of the world other than the US, Liberia, and Myanmar.

Chefs and cooks use grams for accurate measuring. Grams are considered more accurate than cups in terms of units of measurement. This is because lumps or humidity do not affect the accuracy of measuring in grams. Cups, however, are likely to give an inaccurate view when dealing with lumps.

Beyond the culinary world, grams are used a lot in science and medicine.

What Is An Ounce?

As old as the Roman times, ounces are used to weigh out mass, volume, and weight. Ounces are mainly used in the United States. The rest of the world, other than Liberia and Myanmar, has adopted grams as their primary unit of weight measurement.

When it comes to working out how many grams are in an ounce, it is best to use a scale to measure ounces. A scale will offer the best conversion solution for anyone unfamiliar with ounces.

American Standard Versus Worldwide

Grams are not commonly found in American recipes. Instead, the US uses ounces as a way to measure out ingredients for food preparation.

When working with recipes from around the world, it is important to understand how to switch from grams to ounces.

Modern day scales are designed for kitchen use. Many of these scales can switch between ounces and grams. This is the simplest way to accurately measure out in a different metric.

How To Measure Dry Weight

As mentioned earlier, using a kitchen scale designed to measure in ounces and in grams is the simplest to measure ingredients. This is the best and most accurate weight to measure dry ingredients like flour and sugar.

Steps to measuring ingredients with a scale:

  1. Place the bowl on the scale.
  2. Turn the scale on.
  3. Select either ounces or grams.
  4. On the scale, select “tare”. This will zero the scale.
  5. Pour your ingredients (or scoop) slowly into the bowl until the desired measurement is reached.

Difference between Imperial and Metric Systems of Measurement

Here are some quick conversions to refer to when switching between metric and imperial systems:


  • Meters – Inches (1 meter = 39.37 inches)
  • Centimeters – inches (1 cm = 0.29 inches)
  • Millimeters – inches (1 mm = 0.039 inches)


  • Grams – ounces (1 g = 0.035 ounces)
  • Kilograms – pounds ( 1kg = 2.2 pounds)


  • Millileter – US fluid ounces (1 ml = 0.034 fl oz)
  • Liters – quarts ( 1 L = 1 US quart)

Another standard conversion is Celsius to Fahrenheit. This is also highly relevant in cooking and baking. The US uses Fahrenheit as a unit of measure, whereas other parts of the world use Celsius.

  • 130°C = 250°F
  • 150°C = 300°F
  • 190°C = 375°F 
  • 200°C = 400°F 
  • 230°C = 450°F
