Kilograms and grams are the most common measures of weight in the metric system. We use it when we are buying groceries and vegetables. It is used to assess the weight of a person or animal. Over 195  countries in the world besides Liberia, the USA and Myanmar use the metric system of measure for weight and mass. The gram is the smaller measure and is suitable for light objects. The kilogram is used for heavier items and standard mass units in most countries. If you are wondering, How many grams in a kilogram? There are over 2 pounds in kg and 100 gm to kg. Some common uses of these weights are discussed in this article. 

Everyday use of grams and kilograms

Shopping and Grocery Lists

Products like grains, dry fruits, fresh produce, meat etc. are sold in kilograms. Some of the more expensive spices such as saffron and cinnamon are sold by the gram. Prices are generally expressed in kilograms. Whether you shop at a supermarket, local shop, or street side vendor in wholesale or retail, the measures used are generally kilograms and grams. For example:

  • Onion bags are sometimes sold at wholesale prices of Rs. 100/10kg 
  • Masalas such as garam masala, chilli powder, peri peri etc. are sold at 100 grams

Nutrition and Food Labels

Social media influencers such as the FoorPharmer, nutritionists and fitness instructors are increasingly raising awareness of reading the nutrition label at the back of the package. This chart was mostly referred to by professional sports persons, but with greater consumer awareness and understanding of the role of nutrition for good health, more people are checking the nutrition chart. Understanding grams helps you read nutrition labels effectively. For instance, for an apple, the nutritional fact looks like

Fitness and Health

India’s star international footballer said he hadn’t had a meal for taste since he decided to become a professional footballer. Virat Kohli follows a regulated diet of vegan meals for health and fitness. India’s golden athlete, Neeraj Chopra’s diet chart is exceptional and designed to help him meet his goal for excellence. 

Dieticians, fitness instructors, coaches and nutritionists recommend the ideal weight and how many grams of different meals to consume to meet the daily calorie requirement. Understanding grams can help with portion control when preparing meals for a balanced diet.

Cooking and Baking

In cooking and baking, especially in professional cooking, generally, recipes mention ingredient measures in grams and kilograms. For example:

  • A typical bread recipe might call for 500 grams of flour
  • Baking often requires precise amounts, like 200 grams of sugar for besan ladoos

Where they are expressed in tablespoons, teaspoons or cups, there are conversion tables that convert grams and kilograms to cups and spoons. The internet has converters and one can even use measuring cups that have conversion tables printed on them. 

Science Experiments

In science classes and lab experiments, grams and kilograms are frequently used for measurements. For example:

  • Measuring chemicals in grams for a lab experiment.
  • Weighing objects to calculate density, where precision is key.

For instance,  the mass of a glass is measured to be 12.456 grams. If 10.33 grams of water are added to this glass, what is the total combined mass?

total mass = 12.456 g + 10.33g

       = 22.786g 

Environmental Awareness

Though waste is measured in metric tonnes, at the household level, one can measure weight for recycling in kilograms. When the waste collector/ kabadiwala comes to take old newspapers, cardboard or metal from home, they pay in per kg rate. So, the price of a 1kg newspaper can be quoted at around Rs. 10/kg. 

When the doctor has to measure how much dose of medication is to be administered to a patient. How much an elephant that must be transported from the veterinary hospital to the forest weighs and will the truck be able to carry it? Or, how much does the gold bangle weigh? Weights and measures are used in all spheres of life.
