Formula Used
Solid cylinder: V = πr²h, then m = ρV.
Hollow cylinder: V = πh(R² − r²), then m = ρV.
Wall thickness: r = R − t.
Weight force: W = mg.

Frequently Asked Questions
How is cylinder mass calculated?
Calculate cylinder volume first. Multiply that volume by material density. The result gives mass in compatible units.
Can this calculator handle hollow cylinders?
Yes, enter outer and inner dimensions. The internal volume is removed automatically. Wall material mass is then calculated.
What density should I use?
Use density for the exact material grade. Supplier data is usually more accurate. Preset values provide practical general estimates.
Does wall thickness replace inner diameter?
Yes, select the thin-walled cylinder mode. Enter outer size and wall thickness. The calculator derives the inner radius.
Can I include liquid inside a pipe?
Choose the partially filled cylinder mode. Enter fill length and fill percentage. Then select the internal material density.
How are end caps treated?
End caps use the annular cross-sectional area. Their thickness and count determine volume. This volume receives the cylinder density.
What does manufacturing tolerance change?
Tolerance adjusts the calculated mass proportionally. Positive tolerance increases the expected mass. Negative tolerance reduces the expected mass.
Can I compare several materials?
Yes, select materials inside the comparison box. The same geometry is recalculated for each. Results appear beneath the main calculation.
Can layered cylinders use different lengths?
Yes, each layer accepts its own length. Every layer receives separate density settings. Their individual masses are combined.
Why might real mass differ?
Real products contain dimensional and density variations. Coatings, seams, fittings, and moisture also matter. Verify critical work using measured values.
Important Note
This calculator provides engineering estimates from entered values. Actual density and dimensions may vary. Confirm safety-critical results with verified project data.
