Apologies for the newbie question, but when it is written km-1 does that mean (103m)-1 or 103(m-1)?
Thanks in advance!
Thanks in advance!
"km-1" is a unit of measurement called inverse kilometers, which means that it is the reciprocal of kilometers. It is used to measure quantities such as density, frequency, and absorbance.
The units "km-1" can be interpreted as the number of kilometers^-1, or the number of kilometers per unit. For example, if the units are in "km-1/s", it would mean the number of kilometers per second.
"km-1" is commonly used in scientific measurements as it allows for a more precise and accurate representation of quantities. It is particularly useful when dealing with large or small values, as it can avoid the use of very small or large numbers.
Yes, "km-1" can be converted to other units of measurement using conversion factors. For example, "km-1" can be converted to meters^-1 by multiplying by 1000, or to miles^-1 by multiplying by 0.6214.
Some examples of quantities that are commonly measured in "km-1" include molar absorptivity (km-1mol-1), wavenumber (cm-1km), and specific volume (km3/kg).
