It should be worked out as below (nm to mm NOT nm to m) 1mm = 0.001m 1um = 0.001 mm 1 nm = 0.001 um Therefore, 1nm = 0.001 X 0.001 mm (multiplying a nm by 0.001 gives you um, then multiplying this figure by 0.001 again gives you mm = same as dividing no of nanometres by 1000 to give value in micrometres then dividing by 1000 again to give mm ...

Right units go: (biggest to smallest) metres mm um nm to move up by one of those units (ie move up the list), you divide by 1000 because the unit becomes bigger so you have less of them To move down the list, multiply by 1000 (smaller units-more of them) so 4.2 mm--> nm moving down by 2 units so multiply by 1000 twice gives you 4200 x 1000 = 4 200 000 similarly 2.3 um---> …

2024年5月10日 · 1 millimetre (mm) = 10-3 m 1 micrometer (µm) = 10-6 m 1 nanometre (nm) = 10-9 m 1 angstrom (A) = 10-10 m The micro sign is generally done using the Alt Gr key plus M, giving you a µ The "to the power of" elevation in the text is done using the

How do you convert mm to um (and vise versa)? Millimetres are 10 ^-3 metre i.e. a thousandth of a metre Micrometres are 10 ^-6 metre I.e. a millionth of a metre... A million is a thousand thousands...

2024年5月10日 · I know it's confusing. 1 mm = 1000 micrometres, um Now, the epu depends on your magnification. At x40 (x4 and x10) you know 1000 micrometres would be 40epu. at x100, 1000 micrometres would be 100epu 1 epu would be 10 micrometres. The set measurement is 1mm, that is used to help you calibrate. Epu varies on magnification

2017年6月30日 · Then I would measure the diagram and multiply according to that conversion factor.e.g. using your figures, if the scale is 10mm long and the diameter of the diagram is 50 mm, I can then see that the "real" diameter of the particle is 5 times the scale (in this case, 5x20nm = 100nm). Then I convert the diameter of the bacterial cell into the ...

2024年2月1日 · A coil with 20 circular turns each of diameter 60 mm is placed in a uniform magnetic field of flux density 90 mT. Initially the plane of the coil is perpendicular to the magnetic field lines. The coil is rotated about a vertical axis by 90° in a time of 0.20 s so that its plane becomes parallel to the field lines.

2019年5月27日 · 0.004 mm^3 = 0.000004 cm^3 then 1/0.000004 = 250000 250000 x 15 x 1000 = 3.75x10^9 its a sneeky conversion because its mm cubed, so it actually is quite different Oh blast. Definitely something I'm going to need to revise then.

2016年5月8日 · I believe you are referring to a metre rule, not metre ruler. See from the image that the precision is 1mm. With a metre rule, the physical ends of it are literally 0cm and 100cm as you can see in this image: Thus when you place it against an object, one end of the rule (0cm) is already aligned with the end of what you are measuring.

2024年6月19日 · The diameter of the clear area around well D is 18 mm In a different investigation, the student prepared a dilution of the amylase solution. He did this by mixing amylase solution and water in the volumes shown in Table 1. Table 1: Amylase solution / cm3=1.6 Water / cm3 2.4 He prepared a starch-agar Petri dish identical to Figure 7, but with a ...
