1 foot, 1 inch is how many meters?

Normally, reefer container size will be calculated in international length units of feet or inches. However, in Vietnam, people often use the meter as a unit of length. This makes many businesses and investors quite confused in declaring the size of reefer containers when carrying out import-export and transportation cooperation procedures. 

Feet (symbol ft, foot or single comma) is the most popular unit of measurement in the UK, US and around the world. 

1 feet = 30.48cm.

Inches (print symbols or double commas) are also an international unit of length measurement similar to feet.

1 inch = 2.54cm.

Thanks to these conversions, businesses, investors or people in charge of declaring reefer container sizes, carrying out import-export procedures and transport cooperation are easier.

Classification of reefer container sizes

Refrigerated container sizes are currently divided into 5 main types: 10 feet, 20 feet, 40 feet, 45 feet and 50 feet. 

Refrigerated containers, also known as insulated containers, are specialized for carrying items that require maintaining a certain temperature such as frozen, fresh foods and medical products. 

Insulated containers are usually lined with a thick layer of insulation, and the floor is made of aluminum with a T-shaped structure that allows air to circulate evenly in the container, helping to maintain a stable temperature. Therefore, the size of the refrigerated container inside will be smaller than that of dry or general merchandise containers.
