Diregarding the numbers, the order of size of measurements (from largest to smallest) is miles > Yards > Feet > Inches. So any measurements in inches will be the most precise.
foot is the most precise way to measure any unit
Both are units of measure. Neither is more 'precise'. The precision is to do with the accuracy of the measurement taken and not by the units used.
The smallest one - but it makes sense only if you have means of measuring to that precision. Also, more precise is not the same as more appropriate. For example, a micrometre is more precise than a kilometre (by a factor of one billion) but if it makes no sense at all to measure the distance between two cities in micrometres! Or, a microgram is more precise than a kilogram (again by a factor of a billion), but it makes no sense to measure my mass in micrograms. My mass will increase by more than that after I've had a mug of coffee!
cm most likely if you want to be precise. but meters if you are making an estimate.
Both are precise, but in different contexts. An ounce is a smaller measure so 6 oz has a greater absolute precision. On the other hand, 320 is accurate to 2 significant figures so 320 lbs has greater relative precision.
foot is the most precise way to measure any unit
Yes. To be precise, the wavelength is the length of one precise cycle, and one way to measure that is from top to top.
When you estimate you guess the size of something, but when it is precise you have to actually measure it, e.g with a ruler.
The most accurate photo distance measure available for capturing precise measurements in photography is a laser rangefinder.
5 gallons
The most precise is the smallest: the cup.
To measure crown molding accurately for precise installation, use a tape measure to measure the length of each wall where the molding will be installed. Add these measurements together to determine the total length needed. Next, use a miter saw to cut the molding at the correct angles for the corners of the room. Be sure to measure and mark the molding carefully before cutting to ensure a precise fit during installation.
Both are units of measure. Neither is more 'precise'. The precision is to do with the accuracy of the measurement taken and not by the units used.
the ruler is straight and the string is not so it makes it harder for you to measure the string
The answer depends on the graduations marked on the ruler.
To accurately read tape measure lines for precise measurements, start by identifying the whole inch markings. Then, locate the nearest 1/8, 1/4, 1/2, or 3/4 inch marking for more precise measurements. Ensure the tape measure is straight and aligned with the object being measured for accuracy.
It is used to measure very precise amounts of liquids in scientific experiments.
