- When you measure an object with a Vernier caliper, the Vernier scale will slide to the right.
- Read the large number division first from the main scale to the left of the “zero” of the Vernier scale.
- Find the largest whole inch mark to the left side of this index line.
How do you read thousandths of an inch?

What is a micrometer used for?
A micrometer is a measuring instrument that can make extraordinarily precise measurements. Most micrometers are designed to measure within one one-thousandth of an inch! That’s a close fit. Exact measurements like this are necessary when even the smallest of space between objects can cause problems or difficulties.
What does 1cm look like?
1 centimeter is equal to 0.3937 inches, or 1 inch is equal to 2.54 centimeters. In other words, 1 centimeter is less than half as big as an inch, so you need about two-and-a-half centimeters to make one inch.

How long is 1 cm on a ruler?
Each centimeter is labeled on the ruler (1-30). Example: You take out a ruler to measure the width of your fingernail. The ruler stops at 1 cm, meaning that your nail is precisely 1 cm wide. So if you counted five lines from 9 cm, for instance, you’d get 9.5 cm (or 95 mm).

Is a 5mm breast nodule big?
In T1a breast cancer, the tumor size is less than or equal to 5 millimeters (mm); in T1b, the tumor size is greater than 5 mm, but less than or equal to 10 mm. T1a and T1b breast cancers without lymph node spread have excellent long-term outcomes, with more than 95% of women alive at 10 years.
What is the survival rate of invasive ductal carcinoma?
The average 5-year survival rate for women with non-metastatic invasive breast cancer is 90%. The average 10-year survival rate for women with non-metastatic invasive breast cancer is 84%. If the invasive breast cancer is located only in the breast, the 5-year survival rate of women with this disease is 99%.
How curable is invasive ductal carcinoma?
Ductal Carcinoma In Situ is very early cancer that is highly treatable, but if it’s left untreated or undetected, it can spread into the surrounding breast tissue.
Are breast nodules common?
If you find a breast lump or other change in your breast, you might worry about breast cancer. That’s understandable. But breast lumps are common, and most often they’re noncancerous (benign), particularly in younger women.
Can breast nodules go away?
Generalized lumpiness was once thought to be abnormal and was even called fibrocystic breast disease, but it is so common that it is now considered normal. Breast lumpiness usually goes away after menopause but may be found in women who are taking hormone therapy after menopause.
How can you tell the difference between a lump and breast tissue?
If the lumpiness can be felt throughout the breast and feels like your other breast, then it’s likely normal breast tissue. However, if you find any lumps that feel harder or different from the rest of the breast you should have them checked by a professional.
What is a nodule in the breast?
