To convert cubic inches to register tons, multiply the value by 5.78704 × 10⁻⁶. To go the other way, multiply register tons by 172,800 to get cubic inches.
| Cubic Inches (in³) | Register Tons (RT) |
|---|---|
| 1 in³ | 5.78704 × 10⁻⁶ RT |
| 2 in³ | 1.15741 × 10⁻⁵ RT |
| 5 in³ | 2.89352 × 10⁻⁵ RT |
| 10 in³ | 5.78704 × 10⁻⁵ RT |
| 20 in³ | 0.000115741 RT |
| 50 in³ | 0.000289352 RT |
| 100 in³ | 0.000578704 RT |
| 500 in³ | 0.00289352 RT |
| 1,000 in³ | 0.00578704 RT |
25 in³ × 5.78704 × 10⁻⁶ = 0.000144676 RT
Try this example →250 in³ × 5.78704 × 10⁻⁶ = 0.00144676 RT
Try this example →Cubic inch (in³). A cubic inch is 16.387 mL, used for engine displacement in the US.
Register ton (RT). A register ton is 100 cubic feet (2.832 m³), the unit of ship internal volume.
There are 5.78704 × 10⁻⁶ register tons in one cubic inch.
Multiply the number of cubic inches by 5.78704 × 10⁻⁶. For example, 10 cubic inches equal 5.78704 × 10⁻⁵ register tons.
One register ton equals 172,800 cubic inches.
