- An everyday estimate: type your own numbers and the tool does the math. Always round up a little for real-life purchases.
- Area / volume / perimeter
- Perimeter = distance around a shape. Area = the flat space inside it (m²). Volume = the space inside a 3D object (m³).
- Trim / speed (video)
- Trimming cuts off the parts you do not need. Changing speed makes the video faster or slower.
