Enter information in left column; select appropriate menus. Click Calculate. To calculate net kcalories expended subtract Calories of activity that otherwise would have been performed from Calories of activity actually performed. [Example: 230 kcal (Walking) - 50 kcal (Sitting) = 180 net kcalories expended] 1 Calorie = 1 kcalorie = 4.18 kjoules.
A utility locator uses maps, schematics, and hand-held electronic devices to identify underground utility lines. He or she marks points with paint or flags to inform construction workers and homeowners of their exact locations.
Once a pipe is found, the utility locator usually puts a flag directly above it. Many regions and companies have universal color-coding systems that locators must follow to designate the type of underground line. For example, sewer pipes may be marked with green flags and power lines with red flags.
