Material Weight & Volume Calc

Calculate the weight, length, volume, quantity and estimated cost of materials in seconds.

Material Calculator is a practical tool for engineers, fabricators, machinists, manufacturers, buyers, students and DIY users. Select a shape, choose a material, enter the dimensions and get the result without manual formulas.

Calculate by dimensions or weight

• Find weight from dimensions and length
• Find the required length from a known weight
• Calculate volume and number of pieces
• Estimate cost using price per kilogram
• View paintable surface area for supported shapes

Supported shapes

Hexagon, round bar, pipe, square bar, square tube, octagon, flat bar, sheet or plate, channel, sphere, triangle bar and angle.

Metals, plastics and ceramics

Use built-in density values for common materials such as steel, aluminum, copper, iron, gold, silver, titanium, polymers, plastics and ceramics. Need a special alloy or material? Add a custom material and enter its density.

Common uses

Use the app for steel, aluminum, pipe, tube, bar, sheet, plate, plastic and ceramic weight calculations. It is useful for metalworking, fabrication, machining, construction, engineering, manufacturing, education, material purchasing and workshop estimates.

Why use Material Calculator?

• Fast and simple input
• Calculation by length or by weight
• Multiple material categories and shapes
• Remembers your settings
• Works offline
• Lightweight and efficient

Results are estimates based on the selected density and the dimensions and units entered. Material density can vary by grade, alloy, composition and temperature. Verify critical engineering, safety or purchasing calculations.
