convert .621 hl to liters

.013 dl to liters

.00078 mg to kg

2.45 g to cg

1.9 km to cm

.0476 mm to dam

6.4 ul to nl

need conversion and scientific notation before I can proceed from there to the lesson. This was part of an intro that I missed due to illness. Thanks.

so converting 0.621 hl to liters would be 62.1 L? what about scientific notation in that case?

You went up. You move the decimal point to the left. Did you move it to the left? Be sure and read Bob Pursley's answer, too. That is a different approach and you may like it better. Furthermore, the system works when you get out of converting units. That site also provides information on scientific notation.

has good info on scientific notation.

For conversion, I recommend unit conversion,

To convert .621 hl to liters, you can use the conversion factor: 1 hectoliter (hl) = 100 liters.

So, multiplying .621 hl by 100, you get: .621 hl * 100 = 62.1 liters.

To express this in scientific notation, notice that 62.1 can be written as 6.21 x 10^1. Therefore, in scientific notation, .621 hl is 6.21 x 10^1 liters.

Moving on to the next conversion:
To convert .013 dl to liters, we can use the conversion factor: 1 deciliter (dl) = 0.1 liters.

So, multiplying .013 dl by 0.1, you get: .013 dl * 0.1 = 0.0013 liters.

In scientific notation, 0.0013 can be written as 1.3 x 10^(-3). Therefore, in scientific notation, .013 dl is 1.3 x 10^(-3) liters.

For the third conversion:
To convert .00078 mg to kg, we can use the conversion factor: 1 milligram (mg) = 0.000001 kilograms.

So, multiplying .00078 mg by 0.000001, you get: .00078 mg * 0.000001 = 0.00000000078 kilograms.

In scientific notation, 0.00000000078 can be written as 7.8 x 10^(-13). Therefore, in scientific notation, .00078 mg is 7.8 x 10^(-13) kilograms.

Moving on to the fourth conversion:
To convert 2.45 g to cg, we can use the conversion factor: 1 gram (g) = 100 centigrams (cg).

So, multiplying 2.45 g by 100, you get: 2.45 g * 100 = 245 centigrams.

In scientific notation, 245 can be written as 2.45 x 10^2. Therefore, in scientific notation, 2.45 g is 2.45 x 10^2 centigrams.

For the fifth conversion:
To convert 1.9 km to cm, we can use the conversion factor: 1 kilometer (km) = 100,000 centimeters (cm).

So, multiplying 1.9 km by 100,000, you get: 1.9 km * 100,000 = 190,000 centimeters.

In scientific notation, 190,000 can be written as 1.9 x 10^5. Therefore, in scientific notation, 1.9 km is 1.9 x 10^5 centimeters.

Moving on to the sixth conversion:
To convert .0476 mm to dam, we can use the conversion factor: 1 millimeter (mm) = 0.0001 decameters (dam).

So, multiplying .0476 mm by 0.0001, you get: .0476 mm * 0.0001 = 0.00000476 decameters.

In scientific notation, 0.00000476 can be written as 4.76 x 10^(-6). Therefore, in scientific notation, .0476 mm is 4.76 x 10^(-6) decameters.

Lastly, for the seventh conversion:
To convert 6.4 ul to nl, we can use the conversion factor: 1 microliter (ul) = 1,000 nanoliters (nl).

So, multiplying 6.4 ul by 1,000, you get: 6.4 ul * 1,000 = 6,400 nanoliters.

In scientific notation, 6,400 can be written as 6.4 x 10^3. Therefore, in scientific notation, 6.4 ul is 6.4 x 10^3 nanoliters.

I apologize for the previous incomplete explanations. I hope this helps clarify the conversions and scientific notation for you.
