You can use a pocket calculator.
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).
Decibels are a unit of measurement used to express the intensity of sound. They are not considered either imperial or metric, as they are a logarithmic unit that does not directly correspond to physical dimensions like length or weight.
There are 10 decibels in 1 Bel. The Bel is a logarithmic unit used to compare the ratio of two power levels, with the decibel being a more commonly used fraction of the Bel.
by loudness decibels by frequency hertz by wavelength any power of meter
listening to loud audio for a long period time can decibels your ears.
The abbrevation used for decibels is dB.
To convert dB to dBi (decibels isotropic), you need to add 2.15 dB to the dB value. This adjustment accounts for the difference in reference points used in the two scales. So, if you have a value of x dB, the equivalent value in dBi would be x + 2.15 dBi.
The loudness or volume of music is measured in decibels. Decibels are a unit used to quantify the intensity of sound.
Here you find the formula to convert voltage levels to decibels. Scroll down to related links and look at "How to calculate dB?"

Decibels
"Decibels"
Sound is measured in units called decibels (dB). Decibels quantify the intensity or loudness of sound and are used to compare different levels of sound from quiet to loud.
15 subwoofers would produce 15 times as much power. log1015 = 1.176; to convert that to decibels, you have to multiply it by 10, so you get an increase of 11.76 decibels, in other words, 180 + 11.76 = 191.76 decibels. Since the 180 decibels probably includes some rounding, it makes sense to round the final result, too - for example, to 192 decibels.
Decibels (dB) is a unit used for measuring the intensity of a sound or the power of an electrical signal. Without specific context or reference levels, it is not possible to convert 100 kHz to dB as they are different units of measurement (frequency vs decibels).
' kHz ' and ' decibels ' are units for measuring completely different quantities. Neither one can be converted to the other one, any more than you can convert ' 30 miles per hour ' into dollars and cents.
