Knowra Tape measure Tape measure A flexible strip marked with units of length, used to measure distances, dimensions, or body measurements. Its flexibility allows it to follow curves and measure around objects.
Graduated scale : A sequence of marks and numbers that represents measured values along an instrument. The scale converts the tape’s length into readable units.
Retractable tape measure : A tape measure whose blade extends from and retracts into a compact case. It is the common design for measuring dimensions on building sites and in workshops.
Length : A physical quantity describing the extent of an object or the distance between points. A tape measure is designed to measure this quantity.
Ruler : A straight, rigid measuring tool marked with units of length. A ruler measures straight short spans but cannot follow curves like a tape.
Measurement error : The difference between a measured value and the value being measured. Reading angle, tape tension, and alignment can all alter a tape measurement.
Sewing tape measure : A flexible, usually non-retracting tape used for sewing and garment measurements. Its soft strip follows body contours and curved fabric edges.
Metric system : A decimal system of measurement based on the metre and related units. Metric tape markings commonly show millimetres, centimetres, and metres.
Yardstick : A rigid rod marked in units of length, traditionally one yard long. Its rigidity aids straight measurements but prevents wrapping around objects.
Parallax : An apparent shift in an object's position caused by viewing it from different angles. Viewing a tape marking obliquely can shift the apparent reading.
Body measurement : The measurement of dimensions or circumferences of a human body. Flexible tapes measure waist, chest, limb, and other body dimensions.
