<h3>Further explanatio n </h3>7 main quantities have been determined based on international standards, namely:
- 1. Length, meters (m)
- 2. Time, second (s)
- 3. Mass, kilograms (kg)
- 4. Temperature, kelvin (K)
- 5. Light intensity, candela (cd)
- 6. Electric current, amperage (A)
- 7. Amount of substance, mol (m)
Mass is one of the principal quantities, which is related to the matter in the object (how much matter is in an object)
The main mass unit consists of 7 units of other than other units of mass such as quintals, tons, pounds, ounces:
- Kilogram, kg
- Hectogram, hg
- Decagram, dag
- gram, g
- Decigram, dg
- centigram, cg
- milligrams, mg
Each unit descends then multiplied by 10, and if one unit increases then divided by 10
Conversion of other mass units:
- mg milligrams = 10⁻³ g
- kg kilograms = 10³ g
- µg micrograms (mcg) = 10⁻⁶ g
- Mg megagrams (tons) = 10 g
- ng nanograms = 10⁻⁹ g
- Gg gigagram = 10⁹ g
- g picogram = 10⁻¹² g
For US standart mass , the most common units are
- Ounces
- Pounds
- Tons
The conversions between those units are :
1 pound = 16 ounces
1 ton = 2,200 pounds = 32,000 ounces
so :
1 pound = 0,000453592 ton
Three dump trucks are carrying topsoil
Truck A carries 3,545 lb, Truck 8 carries 1,758 lb, and Truck C carries 3,697 lb
Total mass from three dump trucks are :
= 3,545 + 1,758 + 3,697
= 9000 lb
Convert this to tons become :
= 9000 lb x 0.000453592
= 4.082328 ton
