Cement Bag Volume Calculator (50 kg): Step-by-Step Calculation in m³, CFT & Liters

Introduction

Understanding the volume of a cement bag is important for concrete mix calculations, estimation, and site work. In this article, we will calculate the volume of a 50kg cement bag in cubic meters, cubic feet, and litres using a simple step-by-step method.

Basic Data Required

To calculate the volume of a cement bag, you should know the following standard values:

• Density of cement = 1440 kg/ m³
• Weight of one cement bag = 50 kg
• 1 m³ = 35.3147 cubic feet (CFT)
• 1 m³ = 1000 liters

Let’s see how we can calculate the volume of 1 cement bag by using all the values mentioned above.

Step 1: Volume of cement bag in cubic meters (m³)

Number of cement bags required in 1 m³ = Weight of cement in 1 m³/weight of cement in one bag

Number of cement bags required in 1 m³ = 1440/50 = 28.80 No’s

So, Volume of one cement bag = 1/28.8 = 0.034722 m³

Step 2: Volume of cement bag in cubic feet (CFT)

We know:

1 m³ = 35.3147 cubic feet

and 1 m³ = 28.80 No. of bags 

So, Volume of one cement bag = 35.3147/28.80 = 1.226 CFT (cubic feet)

Step 3: Volume of cement bag in Litres

Since: 1 m³ = 10³ liters

Volume of one cement bag = 0.0347 m³ = 0.034722 x 1000 = 34.4722 litres 

∴ Volume of one cement bag = 34.4722 litres 

Final Summary

Unit	Volume of 1 Cement Bag
m³	0.03472 m³
CFT	1.226 CFT
Litres	34.72 Litres

Important Note

The actual volume may slightly vary depending on the following factors

• Cement type (OPC/PPC)
• Moisture content
• Packing density
