At average [[Gravity of Earth|gravity on Earth]] (conventionally, <math>g_\text{n}</math> = {{val|9.80665|u=m/s2}}), a kilogram mass exerts a force of about 9.81&nbsp;N. 
* An average-sized [[Isaac Newton#Apple incident|apple]] with mass 200&nbsp;g exerts about two newtons of force at Earth's surface, which we measure as the apple's [[weight]] on Earth.
: <math>0.200 \text{ kg} \times 9.80665 \text{ m/s}^2 = 1.961\text { N}. </math>
* An [[Human body weight#Average weight around the world|average adult]] exerts a force of about 608&nbsp;N on Earth.
: <math>62\text { kg} \times 9.80665 \text{ m/s}^2=608\text{ N} </math> (where 62&nbsp;kg is the world average adult mass).<ref>{{cite journal |last1=Walpole |first1=Sarah Catherine |last2=Prieto-Merino |first2=David |last3=Edwards |first3=Phillip |last4=Cleland |first4=John |last5=Stevens |first5=Gretchen |last6=Roberts |first6=Ian |display-authors=2 |date=18 June 2012 |title=The weight of nations: an estimation of adult human biomass |journal=[[BMC Public Health]] |volume=12 |issue=12 |page=439 |doi=10.1186/1471-2458-12-439 |pmc=3408371 |pmid=22709383 |doi-access=free }}</ref>
