You can use the same units (energy units) for both.
Farmers commonly use measurement units such as bushels, pounds, acres, and gallons to quantify quantities of crops, livestock, and land area. Additionally, they may use metrics like inches for planting depth and bushels per acre for yield measurements.
The United States primarily uses the Imperial system of measurement, which includes units like inches, feet, and gallons. However, the Metric system is also widely used in scientific, medical, and engineering fields.
I would use my legs, not a measurement! To measure the distance, I would use metres.
America uses the customary units f measurement.
Units of measurement are useful to rationally measure anything.
SI units is what we use in the United States for the common unit of measurement for matter.
when one scientist tells another scientist that something is certain length, that measurement should mean the some thing to both of them.
base on what you measure to use the metric units.
meters
You can use astronomical units or light years.
to check the measure size
Centimetres are units used for the measurement of lengths (or distances).
Metric units of measurement are more fun to say.
Imperial measurement is in general use. Engineers, scientists etc use the SI system.
Gramm (g) Weird countries sometimes use other units such as ounces or pounds.
