Cubic Meter Calculator

To calculate cubic meters (m³), multiply length × width × height in meters. Formula: m³ = L × W × H (all in meters). Example: a box measuring 2m × 1.5m × 1m = 3 m³. If dimensions are in centimeters: divide each by 100 first (1 cm = 0.01 m). If in feet: multiply the result in ft³ by 0.0283168 to get m³. For irregular shapes, break into rectangular sections and add their volumes together. This is the standard method for shipping (CBM), construction, and storage calculations.

1 cubic foot equals 0.0283168 cubic meters. To convert ft³ to m³, multiply by 0.0283168. Examples: 100 ft³ = 2.8317 m³, 500 ft³ = 14.158 m³, 1,000 ft³ = 28.317 m³. To convert m³ to ft³, multiply by 35.315: 1 m³ = 35.315 ft³, 10 m³ = 353.15 ft³. Quick mental math: divide ft³ by 35 to get approximate m³. A typical washing machine is about 0.5-0.8 m³. A standard shipping container (20 ft) has about 33 m³ of internal volume.

CBM stands for Cubic Meter and is the standard unit for international freight volume. Formula: CBM = Length(m) × Width(m) × Height(m). For air freight: 1 CBM = 167 kg (chargeable weight). For sea freight: 1 CBM = 1,000 kg. Shipping costs are based on the greater of actual weight or volumetric weight (CBM × factor). Example: A pallet 1.2m × 1m × 1.5m = 1.8 CBM. If actual weight is 500 kg but volumetric is 1.8 × 167 = 300.6 kg, the charge uses actual weight (500 kg).

1 cubic meter equals exactly 1,000 liters. This is a clean conversion because the metric system is designed that way. Formula: Liters = m³ × 1,000. Examples: 1 m³ = 1,000 L, 2.5 m³ = 2,500 L, 0.5 m³ = 500 L. Reverse: m³ = Liters ÷ 1,000. Common references: A standard bathtub holds about 0.3 m³ (300 L). A 1,000-liter water tank is exactly 1 m³. A swimming pool measuring 10m × 5m × 2m = 100 m³ = 100,000 L (100,000 liters).
