It depends on what you are trying to measure. Measuring the length of a playing field in centimetres will give absurdly large numbers whereas in metres the number will be sensible. On the other hand, the length of a paper clip is best measured in centimetres.
You could use cm, meters (eg. 0.18cm ) or millimetres . A mix of cm and mm should be best for accuracy .
Cm
1 hand equals 0.1016 meter.
A centimetre is smaller than a kilometre.A centimetre is roughly the width of a finger. A kilometre is approximately the same length as one thousand seven-year-olds.True storyx x x x x
50*50 ft = 2500 ft is a measure of length, not area. It would not be appropriate to convert a length into an area. 50ft * 50 ft, on the other hand, is a measure of an area and is equivalent to 232.26 sq metres (to 2 dp).
A hand is a unit of measurement that is typically used with horses. A hand is equivalent to four inches. To measure the height of a horse, measure from the top of the withers (high point where the mane starts on the back) down to their legs.
As far as using a practical unit, centimeters would indeed be effective in measuring a hand.
You would be more likely to measure a fish tank in centimeters because it is typically smaller and requires more precise measurements. A swimming pool, on the other hand, is usually larger and would be measured in meters or feet.
Mass is the measure of the weight of an object (grams, pounds, ect.) whereas length is the measure of the distance from one endpoint to another (inches, meters, ect.).
A gram is a measure of weight, a centimetre is a measure of distance. So, coffee is sold by gram. Unless you are having a short or a long black
Absolutely. Photographic light meters are designed to measure light for photographic exposure (in a film-speed/shutter-speed/aperture combination), but many hand-held photo light meters can measure light in footcandles, which is a common scale. If you look on places like eBay, you can find inexpensive, digital, brand new meters which read out in Lux or Lumens. Some may read in footcandles as well. It's not difficult to convert from one measure to another (there should be internet calculators which would do it easily).
