If the scale is calibrated in tenths of a kilogram I do not see how you can estimate to the nearest two hundredths of a kilogram!
The calibration allows you to measure mass (in kilograms) to 1 decimal place. For masses less than 10 kg, that mean 2 significant figures. For masses of 10 kg or more but less than 100 kg, you can give the information to 3 sf and for masses of 100 kg or more, 3 sf.
int num = 12345; int lastDigit = num % 10; // = 5
The rules for identifying significant figures when writing or interpreting numbers are as follows: All non-zero digits are considered significant. For example, 91 has two significant figures (9 and 1), while 123.45 has five significant figures (1, 2, 3, 4 and 5). Zeros appearing anywhere between two non-zero digits are significant. Example: 101.1203 has seven significant figures: 1, 0, 1, 1, 2, 0 and 3. Leading zeros are not significant. For example, 0.00052 has two significant figures: 5 and 2. Trailing zeros in a number containing a decimal point are significant. For example, 12.2300 has six significant figures: 1, 2, 2, 3, 0 and 0. The number 0.000122300 still has only six significant figures (the zeros before the 1 are not significant). In addition, 120.00 has five significant figures since it has three trailing zeros.
The best estimate suggests that about 50-60% of the variation in intelligence can be explained by genetics. This means that genetic factors play a significant role in determining an individual's level of intelligence, but environmental factors also play an important role.
Two significant figures are justified in this measurement. Since the measuring device ruler has smallest divisions of 0.1 cm, the uncertainty lies in the last digit. The measurement falls between 9.0 cm and 10.0 cm, so the two digits, 9 and 0, are significant.
To increase the number of significant figures in a measurement, you can estimate between the smallest markings on the measuring device. For example, if a device measures to the nearest 0.1 unit, you can estimate to the nearest 0.01 unit to increase the number of significant figures.
no. you can estimate by using an oven therometer

Molecular clocks are typically calibrated by comparing genetic mutations or fossil records to estimate the rate at which DNA changes over time. This helps scientists determine how long ago species diverged from a common ancestor.
to 1 significant digit: 8000 2 significant digits: 7700 3 significant digits: 7660 4 significant digits: 7656. 5 significant digits: 7656.0 6 significant digits: 7656.00 and so on and so forth for forever..........
4.11, to the justified number of significant digits.
Given conditions of standard temperature and pressure, and measuring in standard units with calibrated mensuration devices in a controlled laboratory environment, the best current estimate is precisely 32 of them.
For an "estimate", I would suggest rounding it to one or two significant digits.

No, 'estimate' means to guess the value of something, while 'round' means either circular or is a process for truncating a value to fewer significant figures.
For a quick estimate, you would usually round to one, sometimes to two, significant digits. One significant digit means discarding all digits after the first, i.e., converting them to zero (and rounding the remaining digit up or down as appropriate).
The calculator already gives you a square root (or other root) with 8 or 10 significant digits, and does so quickly; there is no need to "estimate". However, you can round the result if you like.
236+710 = 946. Rounded to 2 significant digits, that is 950, rounded to one sd, it is 900.
