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).

What is the unit of sound to measure?
by loudness decibels by frequency hertz by wavelength any power of meter
Are decibels imperial or metric?
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.
What can be used to convert decibels?
To convert decibels to a linear scale, you can use the formula: linear value = 10^(decibels / 10). Conversely, to convert a linear value to decibels, you can use the formula: decibels = 10 * log10(linear value).
How many decibels is 500 Hertz?
Decibels measure the intensity of sound, not the frequency. The perceived loudness of a sound at 500 Hz would depend on factors like the amplitude or intensity of the sound.
Is TV volume measured in dB?
No, TV volume is not measured in decibels (dB). Decibels are used to measure sound intensity or power levels. TV volume is typically measured in units like percentage, levels, or volume units (VU).
