## Gram and Kilogram (G and Kg): The Dynamic Duo of Mass Measurement

• ### One kilogram is equal to 1000 grams.

• The kilogram was originally defined as the mass of one cubic decimeter of water at 4 degrees Celsius. However, this definition was difficult to measure accurately, so in 2019, the kilogram was redefined using a fundamental constant of physics called the Planck constant.
• The kilogram is defined by taking the fixed numerical value of the Planck constant h to be 6.62607015×10⁻³⁴ when expressed in the unit J⋅s, which is equal to kg⋅m²⋅s⁻¹, where the meter and the second are defined in terms of c and ΔνCs.
• The gram is defined as one thousandth of the kilogram.
• The new definition of the kilogram and gram was adopted by the General Conference on Weights and Measures (CGPM) in 2018. It is now the official definition of these units in the International System of Units (SI).
• g: The symbol "g" stands for gram. It is derived from the French word "gramme," which in turn is derived from the Greek word "γράμμα" (gramma), meaning "small weight."
• kg: The symbol "kg" stands for kilogram. It is derived from the French phrase "kilogramme," which is a combination of the prefix "kilo-" (meaning "one thousand") and the word "gramme."
• The kilogram is used to measure the weight of larger objects, such as people, cars, and food.
Grams to kilograms conversion is very useful in many different ways. Here are a few examples:
• In the kitchen: Measuring ingredients in grams is more accurate than measuring them in cups or tablespoons, especially for small quantities. This is because grams are a unit of weight, while cups and tablespoons are units of volume.
• In the lab: Scientists use grams to measure the weight of chemicals and other substances.
• In industry: Grams are used to measure the weight of products, such as screws, nails, and batteries.
• In shipping: Shipping companies use grams to calculate the weight of packages so they can charge the correct shipping rates.
