Newton (SI) and pound-weight (Imperial).
The two units are mass and weight and I can't answer the equal amount
Mass and weight are two different things: you cannot measure the mass of your weight. That is like talking about the temperature of your height - it makes no sense.
In the metric system you use grams, in Standard Units you use ounces, pounds, and tons.
A ounce is a measure of weight, the milliliter is a measure of volume the two units can not be directly equated.
A pound is a unit of mass. A centimetre is a unit of length. The two units are therefore incompatible.
Examples: kilogram, gram, ton, pound.
You can't. Feet are a measure of length/distance. Kilograms are a measure of weight. The two units can not be equated.
These are two different units of measurement. A teaspoon is a measure of volume. A milligram is a measure of weight or mass.
None. Millimeters measure length and ounces measure weight so the two units are not compatable
Lightyears and miles
newtons and centimeters squared
A teaspoon is a measure of capacity, not of weight. Therefore, the two units are incompatible.
