You can find the perimeter of any planar (flat) object using string by wrapping the string around the outside of the object, noting the point on the string where you return to the starting point, and then measuring the length of that portion of the string.
If you have a ruler and a piece of string, you could use the string to find the distance around the bust (or whatever you wanted to measure), mark the point at where the string starts to overlap, then measure the string using the ruler.
Flow can be measured using instruments such as flow meters or by calculating flow rate using the formula Q = A * V, where Q is the flow rate, A is the cross-sectional area of the flow, and V is the velocity of the fluid. Measuring devices like mass flow meters, ultrasonic flow meters, and electromagnetic flow meters are commonly used for measuring flow in various industries.
Some tools used to measure inches include rulers and tape measures. Centimeters can be measured using rulers and tape measures as well. Meters can be measured using meter sticks, measuring tapes, or measuring wheels. Yards are typically measured using yardsticks, tape measures with yard markings, or measuring wheels with yard measurements.

No. You can only measure a person's length using some sort of marked off stick or measuring tape. After you know the person's length, you can describe it in meters if you want to tell others about it.
By using gravity force, a flow meter has many functions. One function is measuring lung capacity and another is measuring fluid by ultra waves. There are various types of flow meters and quit hard to narrow one down.
there is no such method using string copy
You can use any units of distance you want. If you measure the sides of a rectangle using feet, the area will be in square feet (ft²) If you measure using meters the area will be in square meters (m²) Here is an example of the math Area = length x width = 3 meters x 4 meters = 3x4 meters x meters = 12 square meters = 12 meters squared = 12 m²
To measure a distance on a map that exceeds its length, you can use a piece of string or a flexible measuring tool to trace the route along the map. Mark where the string overlaps and then measure the length of the string using a ruler. Alternatively, if the map has a scale, you can calculate the distance in segments, measuring each segment separately and then summing them up. This way, you can accurately determine the total distance despite the map's limitations.
You can measure a curved line on a map by using a string or measuring tape to match the curve and then measuring the length against a ruler or a map scale. Alternatively, you can break down the curve into smaller straight line segments and then add up their lengths to get an estimate.
Running tracks are built today following the guidelines of the IAAF which state that the measuring line measures 400 meters. Using that as a guide, lane 6 will then be 433.38 meters.
