Some Helpful Perspective on Weight, Size, Concentration and Dimension in the nanoscale

Conversion Chart

milli = one thousandth = 10-3 = 0.001

micro = one millionth = 10-6 = 0.000001

nano = one billionth = 10-9 = 0.000000001

pico = one trillionth = 10-12

Weight

Kilogram – 1kg = 1000g

Gram – 1g = 0.001kg

Milligram – 1mg = 0.001g = 1000µg

Microgram – 1µg = 0.001mg = 0.000001g

Nanogram – 1ng = 0.001µg = 0.000001mg

Size:

Meter – 1 m = 1,000mm

Millimeter – 1 mm = 1,000µm = 1,000,000nm = 10-3 m

Micron – 1 µm = 1 millionth of a meter = 0.001mm = 1000nm = 10-6 m

Nanometer – 1 nm = 1 billionth of a meter = 0.001µm = 0.000001mm = 10-9 m

Angstrom – 1 Å = 1 Ångstrom = 0.1nm = 10-10 m

Picometer – 1 pm = 1 trillionth of a meter = 0.001nm = 10-12 m

Concentration:

By Volume

1ng/L = 1ppt ng/L = PPT = 0.0000000001%

1µg/L = 1ppb µ/L = PPB = 0.0000001%

1mg/L = 1ppm mg/L = PPM = 0.0001% = 1µg/mL

1mg/mL = 1,000ppm mg/mL = g/L = 0.1%

1g/mL = 1,000,000ppm = 100%

10g/L = 10,000ppm = 1%

100g/L = 100,000ppm = 10%

Analogies:

PPM : 1 inch in 16 miles or 1 minute in two years

PPB : 1 second in nearly 32 years

PPT : 1 ounce in 7.5 billion gallons of water

1 ppt = 0.001 ppb = 0.000001 ppm

By Weight

100 µg/mg = 100mg/g = 10%

10 mg/g = 10g/kg = 1%

1 g/kg = 1/1000th = 1 µg/mg =1mg/g = 0.1%

1 mg/kg = 1ppm = 1 µg/g = 0.0001%

1 µg/kg = 1ppb = 0.0000001%

1 ng/kg = 1ppt = 0.0000000001%

Water Weight:

Liter – L = 1kg = 100% of a liter

Milliliter – mL = 1gram = 0.1% of a liter

Microliter – µl = 1mg = 0.0001% of a liter (1 millionth of a liter)
